In this study, we solved the Schrödinger wave equation by using effective potential in an artificial neural network (ANN) for the mass spectrum of different charmonium states, including , , , and . The ANN approach provides an efficient, more general, and continuous solution-approximating strategy, thus eliminating the possibility of skipping any region of interest in mass spectroscopy. The close consistency of ANN results with the already-reported results from numerical and theoretical approaches and experimental ones shows the reliability and accuracy of the ANN approach.

Using a data sample of 4.481× 10 8 ψ (3686) events collected with the BESIII detector, we report the first observation of the four-lepton-decays J/ψ→ e+ e− e+ e− and J/ψ→ e+ e− μ+ μ− utilizing the process ψ (3686)→ π+ π− J/ψ. The branching fractions are determined to be [5.48±0.31 (stat)±0.45 (syst)]× 10− 5 and [3.53±0.22 (stat)±0.13 (syst)]× 10− 5, respectively. The results are consistent with theoretical predictions. No significant signal is observed for J/ψ→ μ+ μ− μ+ μ−, and an upper limit on the branching fraction is set at 1.6× 10− 6 at the 90% confidence level. A C P asymmetry observable is constructed for the first two channels, which is measured to be (− 0.012±0.054±0.010) and (0.062±0.059±0.006), respectively. No evidence for C P violation is observed in this process.

New research has highlighted a shortfall in the Standard Model (SM) because it predicts neutrinos to have zero mass. However, recent experiments on neutrino oscillation have revealed that the majority of neutrino parameters indeed indicate their significant mass. In response, scientists are increasingly incorporating discrete symmetries alongside continuous ones for better justification of observed patterns of neutrino mixing. In this study, we have examined a model within symmetry to estimate the neutrino masses using particle swam optimization technique for both mass hierarchy of neutrino. This model employed a hybrid seesaw mechanism, a combination of seesaw mechanism of type-I and type-II, to establish the effective Majorana neutrino mass matrix. After calculating the mass eigenvalues and lepton mixing matrix upto second order perturbation theory in this framework, this study seeks to investigate the scalar potential for vacuum expectation values (VEVs), optimize the parameters, matrix, neutrino masses: , , , , , and , effective neutrino mass parameters: , , and , are predicted for both mass hierarchy through particle swam optimization (PSO), showing strong agreement with recent experimental findings.

Recent research has indicated that the Standard Model (SM), while historically highly effective, is found to be insufficient due to its prediction of zero mass for neutrinos. With the exception of a few, the majority of the parameters related to neutrinos have been determined by neutrino oscillation experiments with excellent precision. Experiments on neutrino oscillation and neutrino mixing have shown that neutrinos are massive. To fill in gaps, discrete symmetries are becoming more common alongside continuous symmetries while describing the observed pattern of neutrino mixing. Here, we present a $T_7$ flavor symmetry to explain the masses of charged leptons and neutrinos. The light neutrino mass matrix is derived using seesaw mechanism of type I, which involves the Dirac neutrino mass matrix as well as the right-handed neutrino mass matrix. We estimate the Pontecorvo-Maki-Nakagawa-Sakata matrix ($U_{PMNS}$), three mixing angles, $\theta_{12}$, $\theta_{23}$ and $\theta_{13}$, which are strongly correlated with the recent experimental results. The extent of $CP$ violation in neutrino oscillations is obtained by calculating Jarskog invariant $(J_{CP})$ on the behalf of $U_{PMNS}$. We also find the masses of three neutrinos and Effective Majorana neutrino mass parameter $\langle m_{ee} \rangle$ which is $1.0960244138965946$ $meV$ and $10.92168920244218$ $meV$ for normal and inverted hierarchy, respectively.

Using a data sample of (1.0087±0.0044)× 10 10 J/ψ decay events collected with the BESIII detector at the center-of-mass energy of s= 3.097 GeV, we present a search for the hyperon semileptonic decay Ξ 0→ Σ− e+ ν e which violates the Δ S= Δ Q rule. No significant signal is observed, and the upper limit on the branching fraction B (Ξ 0→ Σ− e+ ν e) is determined to be 1.6× 10− 4 at the 90% confidence level. This result improves the previous upper limit result by about one order of magnitude.

Using e+ e− annihilation data corresponding to an integrated luminosity of 2.93 fb− 1 taken at a center-of-mass energy of 3.773 GeV with the BESIII detector, we report the first measurements of the branching fractions of the inclusive decays D 0→ π+ π+ π− X and D+→ π+ π+ π− X, where pions from K S 0 decays have been excluded from the π+ π+ π− system and X denotes any possible particle combination. The branching fractions of D 0 (D+)→ π+ π+ π− X are determined to be B (D 0→ π+ π+ π− X)=(17.60±0.11±0.22)% and B (D+→ π+ π+ π− X)=(15.25±0.09±0.18)%, where the first uncertainties are statistical and the second systematic.

Using a sample of (10. 09±0. 04)× 10 9 J/ψ decays collected with the BESIII detector, partial wave analyses of the decay are performed within the invariant mass region below 1.6 GeV/c 2. The covariant tensor amplitude method is used in both mass independent and mass dependent approaches. Both analysis approaches exhibit dominant pseudoscalar and axial vector components, and show good consistency for the other individual components. Furthermore, the mass dependent analysis reveals that the invariant mass spectrum for the pseudoscalar component can be well described with two isoscalar resonant states using relativistic Breit-Wigner model, ie, the η (1405) with a mass of MeV/c 2 and a width of MeV, and the η (1475) with a mass of MeV/c 2 and a width of MeV. The first and second uncertainties are statistical and …

The processes e+ e−→ Δ++ Δ−− and e+ e−→ Δ++ p π−+ c. c. are studied for the first time with 179 pb− 1 of e+ e− annihilation data collected with the BESIII detector at center-of-mass energies from 2.3094 to 2.6464 GeV. No significant signal for the e+ e−→ Δ++ Δ−− process is observed and the upper limit of the Born cross section is estimated at each energy point. For the process e+ e−→ Δ++ p π−+ c. c., a significant signal is observed at center-of-mass energies near 2.6454 GeV and the corresponding Born cross section is reported.

Based on 22.7 fb− 1 of e+ e− annihilation data collected at 33 different center-of-mass energies between 3.7730 and 4.7008 GeV with the BESIII detector at the BEPCII collider, Born cross sections of the two processes e+ e−→ ϕ K+ K− and e+ e−→ ϕ K S 0 K S 0 are measured for the first time. No indication of resonant production through an intermediate vector state V is observed, and the upper limits on the product of the electronic width Γ e+ e− and the branching fraction Br (V→ ϕ K K) of the processes e+ e−→ V→ ϕ K+ K− and e+ e−→ V→ ϕ K S 0 K S 0 at the 90% confidence level are obtained for a large parameter space in resonance masses and widths. For the current world average mass and width of the ψ (4230) of m= 4.2187 GeV/c 2 and Γ= 44 MeV, we set upper limits on the ϕ K+ K− and ϕ K S 0 K S 0 final states of 1.75 and 0.47 eV at the 90% confidence level, respectively.

A precision measurement of the matrix elements for η→ π+ π− π 0 and η→ π 0 π 0 π 0 decays is performed using a sample of (10087±44)× 10 6 J/ψ decays collected with the BESIII detector. The decay J/ψ→ γ η is used to select clean samples of 631, 686 η→ π+ π− π 0 decays and 272, 322 η→ π 0 π 0 π 0 decays. The matrix elements for both channels are in reasonable agreement with previous measurements. The nonzero g X 2 Y term for the decay mode η→ π+ π− π 0 is confirmed, as reported by the KLOE Collaboration, while the other higher-order terms are found to be insignificant. Dalitz plot asymmetries in the η→ π+ π− π 0 decay are also explored and are found to be consistent with charge conjugation invariance. In addition, a cusp effect is investigated in the η→ π 0 π 0 π 0 decay, and no obvious structure around the π+ π− mass threshold is observed.

Based on 7.33 fb− 1 of e+ e− collision data taken at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, we measure the branching fraction of D s*+→ D s+ π 0 relative to that of D s*+→ D s+ γ to be (6.16±0.43±0.18)%. The first uncertainty is statistical and the second one is systematic. By using the world average value of the branching fraction of D s*+→ D s+ e+ e−, we determine the branching fractions of D s*+→ D s+ γ and D s*+→ D s+ π 0 to be (93.57±0.38±0.22)% and (5.76±0.38±0.16)%, respectively.

Using a data sample corresponding to an integrated luminosity of 11.3 fb− 1 collected at center-of-mass energies from 4.23 to 4.70 GeV with the BESIII detector, we observe the process e+ e−→ π 0 π 0 ψ 2 (3823) for the first time with a statistical significance of 6. 0 standard deviations. The ratio of average cross sections for e+ e−→ π 0 π 0 ψ 2 (3823) and π+ π− ψ 2 (3823) is determined to be, which is consistent with expectations from isospin symmetry. Here and below, the first uncertainties are statistical and the second are systematic. The mass of the ψ 2 (3823) is measured to be M [ψ 2 (3823)]= 3824. 5±2. 4±1. 0 MeV/c 2. Due to the limited data sample, an upper limit of 18.8 MeV at 90% confidence level is set on the intrinsic width of ψ 2 (3823).

A partial wave analysis on the process e+ e−→ ωπ+ π− is performed using 647 pb− 1 of data sample collected by using the BESIII detector operating at the BEPCII storage ring at center-of-mass (cm) energies from 2.000 GeV to 3.080 GeV. The Born cross section of the e+ e−→ ωπ+ π− process is measured, with precision improved by a factor of 3 compared to that of previous studies. A structure near 2.25 GeV is observed in the energy-dependent cross sections of e+ e−→ ωπ+ π− and ωπ0π0 with a statistical significance of 7.6 σ, and its determined mass and width are 2232±19±27 MeV/c2 and 93±53±20 MeV, respectively, where the first and second uncertainties are statistical and systematic, respectively. By analyzing the cross sections of subprocesses e+ e−→ ωf0 (500), ωf0 (980), ωf0 (1370), ωf2 (1270), and b1 (1235) π, a structure, with mass M= 2200±11±17 MeV/c2 and width Γ= 74±20±24 MeV, is observed with a combined statistical significance of 7.9 σ. The measured resonance parameters will help to reveal the nature of vector states around 2.25 GeV.[Figure not available: see fulltext.]
