Abstract:

A bstract A data sample collected with the LHCb detector corresponding to an integrated luminosity of 9 fb − 1 is used to measure eleven CP violation observables in B ± → Dh ± decays, where h is either a kaon or a pion. The neutral D meson decay is reconstructed in the three-body final states: K ± π ∓ π 0 ; π + π − π 0 ; K + K − π 0 and the suppressed π ± K ∓ π 0 combination. The mode where a large CP asymmetry is expected, B ± → [ π ± K ∓ π 0 ] D K ± , is observed with a significance greater than seven standard deviations. The ratio of the partial width of this mode relative to that of the favoured mode, B ± → [ K ± π ∓ π 0 ] D K ± , is R ADS( K ) = (1 . 27 ± 0 . 16 ± 0 . 02) × 10 − 2 . Evidence for a large CP asymmetry is also seen: A ADS( K ) = −0 . 38 ± 0 . 12 ± 0 . 02. Constraints on the CKM angle γ are calculated from the eleven reported observables.

Performance of the LHCb RICH detectors during LHC Run 2

Abstract:

The TORCH detector aims to provide K/π (K/p) separation up to a momentum of about 10 (15) [Formula presented] by measuring their time-of-flight at the LHCb detector. Prompt Cherenkov photons are produced in a quartz radiator bar of 10 mm thickness, and propagated via total internal reflection to the periphery of the detector, where they are focused onto an array of microchannel plate photomultipliers that measure the photon arrival time and position. Pattern recognition techniques are used to compare the likelihood that the detector image is due to a given particle hypothesis. Good performance is obtained even for very high detector occupancies
