Improved measurement of the strong-phase difference delta(K pi )(D)in quantum-correlated D(D)over-bar decays( )

Ablikim, M; Achasov, M. N; Adlarson, P.; Albrecht, Malte; Aliberti, R.; Cetin, Ali Serkant; Kolcu, Onur Buğra (SPRINGER, 2022)

The decay D -> K-pi(+) is studied in a sample of quantum-correlated D (D) over bar pairs, based on a data set corresponding to an integrated luminosity of 2.93 fb(-1) collected at the psi(3770) resonance by the BESIII ...
Observation of the Y(4230) and a new structure in e(+)e(-) -> K+ K- J/psi

Ablikim, M.; Achasov, M. N.; Adlarson, P.; Cetin, Ali Serkant; Kolcu, Onur Buğra (IOP Publishing Ltd, 2022)

The cross sections of e(+)e(-) -> K+K- J/psi at center-of-mass energies from 4.127 to 4.600 GeV are measured based on 15.6 fb(-1) data collected with the BESIII detector operating at the BEPCII storage ring. Two resonant ...
Search for a massless dark photon in Λc+ →pγ′ decay

Ablikim M.; Achasov M.N; Adlarson P.; Albrecht M.; Aliberti R.; Amoroso A.; Cetin, Ali Serkant; Kolcu, Onur Bugra (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, ...
