“…Figure 2 shows the invariant mass of the 𝑝𝐾 − 𝜋 + system. No signal event has been observed and thus the UL on the BF is set to be 6.9 × 10 −8 at 90% CL [14], which is more than two orders of magnitude more strict than that of CLEO's measurement in the analogous process. The result is one of the best constraints from meson decays and is consistent with the conclusion drawn from the proton decay experiment.…”

Based on 2.93 fb −1 of 𝑒 + 𝑒 − collision data taken at √ 𝑠 = 3.773 GeV and 1.31×10 9 𝐽/𝜓 events taken at √ 𝑠 = 3.097 GeV, we present the searches for baryon number and lepton number violation in𝑐 𝑒 − + 𝑐.𝑐, and 𝐽/𝜓 → 𝑝𝐾 − Λ + 𝑐.𝑐 decays. No obvious signals are found and the upper limits on the branching fractions of these decays are set to be ∼ 10 −8 − 10 −6 at 90% confidence level. Those results are the most stringent ones to date for these processes but are still far above the prediction of the higher generation model.

“…For example, the branching fractions of the semi-leptonic and hadronic weak decays of the J/ψ are predicted to be less than 10 −9 in the framework of the standard model (SM) [1]. Over the past few years, the BESIII collaboration previously searched for the baryon and lepton number violating decay J/ψ → Λ + c e − [2] and the flavor changing neutral current decay ψ(3686) → Λ + c pe + e − [3], as well as the weak decays J/ψ → D − e + ν e [4] and J/ψ → D ( * )− s e + ν e [5]. Throughout this paper, the charge conjugated channels are always implied.…”

Using (448.1 ± 2.9) × 10 6 ψ(3686) events collected with the BESIII detector, we perform the first search for the weak baryonic decay ψ(3686) → Λ + c Σ− + c.c.. The analysis procedure is optimized using a blinded method. No significant signal is observed, and the upper limit on the branching fraction (B) of ψ(3686) → Λ + c Σ− + c.c. is set to be 1.4 × 10 −5 at the 90% confidence level.

“…The large data samples accumulated by the BESIII experiment lead to the best sensitivity for investigating BNV decays of charmed mesons or charmonium states. The BESIII collaboration searched for BNV in D + → Λ( Σ0 )e + [10] and J/ψ → Λ + c e − + c.c [11] and set ULs at the level of 10 −8 − 10 −6 with no significant signals.…”

Using an electron-positron collision data sample corresponding to an integrated luminosity of 2.93 fb −1 collected with the BESIII detector at a center-of-mass energy of 3.773 GeV, we search for the baryon and lepton number violating decays D 0 → pe + and D 0 → pe − . No obvious signals are found with the current statistics. The upper limits on the branching fractions for D 0 → pe + and D 0 → pe − are set to be 1.2 × 10 −6 and 2.2 × 10 −6 at 90% confidence level, respectively.
