The LHCb upgrade represents a major change of the experiment. The detectors have been almost completely renewed to allow running at an instantaneous luminosity five times larger than that of the previous running periods. Readout of all detectors into an al ...

Measurement of the CKM angle gamma in B-+/- -> DK +/- and B-+/- -> D pi(+/-) decays with D -> K(S)(0)h(+)h(-)

Aurelio Bay, Minh Tâm Tran, Tatsuya Nakada, Guido Haefeli, Olivier Schneider, Chitsanu Khurewathanakul, Axel Kuonen, Olivier Göran Girard, Maxime Schubiger, Brice Emile Maurin, Guillaume Max Pietrzyk, Matthieu Philippe Luther Marinangeli, Lino Ferreira Lopes, Violaine Bellée, Vincenzo Battista, Guido Andreassi, Plamen Hristov Hopchev, Preema Rennee Pais, Pavol Stefko, Maria Elena Stramaglia, Luca Pescatore, Vladimir Macko, Pietro Marino, Tara Nanut, Ana Bárbara Rodrigues Cavalcante, Federico Leo Redi, Michel De Cian, Sebastian Schulte, Veronica Sølund Kirsebom, Elena Graverini, Maria Vieites Diaz

A measurement of CP-violating observables is performed using the decays B-+/- -> DK +/- and B-+/- -> D pi(+/-), where the D meson is reconstructed in one of the self-conjugate three-body final states K-S(0)pi(+)pi(-) and (KSK+K-)-K-0 (commonly denoted K(S) ...
