Search for baryon and lepton number violating decays D+ -> (Lambda)over-bar((Sigma)over-bar(0))e(+) and D+ -> Lambda(Sigma(0))e(+)
(AMER PHYSICAL SOC, 2020)
Using a 2.93 fb(-1) data sample of electron-positron collisions taken with the BESIII detector at a center-of-mass energy of 3.773 GeV, which corresponds to (8296 +/- 31 +/- 64) x 10(3) D+ D- pairs, we search for the baryon ...
Search for a massless dark photon in Λc+ →pγ′ decay
(American Physical Society, 2022)
A search for a massless dark photon γ′ is conducted using 4.5 fb-1 of e+e- collision data collected at center-of-mass energies between 4.600 and 4.699 GeV with the BESIII detector at BEPCII. No significant signal is observed, ...
