Search for ηc (2S) →k+K-η′ decay

Using (2.712±0.014)×109 ψ(2S) events collected with the BESIII detector operating at the BEPCII, we search for the ηc(2S)→K+K-η′ decay. Its decay branching fraction is measured to be (11.11±4.67(stat)±1.82(syst)±4.24(extr))×10-4, where the first uncertaint ...

Amplitude models are applied to studies of resonance structure in D-0 -> (KSK-)-K-0 pi(+) and D-0 -> (KSK+)-K-0 pi(-) decays using pp collision data corresponding to an integrated luminosity of 3.0 fb(-1) collected by the LHCb experiment. Relative magnitud ...

Time-dependent CP asymmetries in the decay rates of the singly Cabibbo-suppressed decays D-0 -> K-K+ and D-0 -> pi (-) pi(+) are measured in pp collision data corresponding to an integrated luminosity of 3.0 fb(-1) collected by the LHCb experiment. The D-0 ...

Bounds on the width, mass difference and other properties of X(3872) -> pi(+)pi(-) J/psi decays

Mingkui Wang, Olivier Schneider, Chao Wang, Yiming Li, Aurelio Bay, Sun Hee Kim, Jun Yong Kim, Remi Léandre Albert Louvot

We present results from a study of X(3872) -> pi pi J/psi decays produced via exclusive B -> KX(3872) decays. We determine the mass to be M-X(3872) = (3871.85 +/- 0.27(stat) +/- 0.19(syst)) MeV, a 90% confidence level upper limit on the natural width of Ga ...
