This paper describes an alternative method of charged hyperon reconstruction applicable to the LHCb experiment. It extends the seminal work of the FOCUS collaboration to the specific detector layout of LHCb and addresses the reconstruction ambiguities reported in their earlier work, leading to improvements in the reconstruction efficiency for the specific cases of Xi- and Omega- baryon decays to a charged meson and a Lambda baryon.
The single electron track-reconstruction efficiency is calibrated using a sample corresponding to $1.3~mathrm{fb}^{-1}$of $pp$ collision data recorded with the LHCb detector in 2017. This measurement exploits $B^+to J/psi (e^+e^-)K^+$ decays, where o
The determination of track reconstruction efficiencies at LHCb using $J/psirightarrowmu^{+}mu^{-}$ decays is presented. Efficiencies above $95%$ are found for the data taking periods in 2010, 2011, and 2012. The ratio of the track reconstruction effi
The rare B decays Bs(d)-->mumu, B-->K*mumu and Bs-->phigamma are studied using up to sim 0.41 fb^{-1} of pp collisions at sqrt{s} = 7 TeV collected by the lhcb experiment in 2010 and 2011. A search for the decays Bs(d)-->mumu, is performed with 0.41
We report the first observation of the doubly-strange baryon $Xi(1620)^0$ in its decay to $Xi^-pi^+$ via $Xi_c^+ rightarrow Xi^- pi^+ pi^+$ decays based on a $980,{rm fb}^{-1}$ data sample collected with the Belle detector at the KEKB asymmetric-ener
The LHCb collaboration has redesigned its trigger to enable the full offline detector reconstruction to be performed in real time. Together with the real-time alignment and calibration of the detector, and a software infrastructure to make persistent
