Measurement of the exclusive Υ production cross-section in pp collisions at √s=7 TeV and 8 TeV
(Springer, 2015)
A study is presented of central exclusive production of Υ(nS) states, where the Υ(nS) resonances decay to the μ + μ − final state, using pp collision data recorded by the LHCb experiment. The cross-section is measured in ...
Measurement of the CKM angle γ using B ± → DK ± with D → K0S π + π −, K0S K + K − decays
(Springer, 2014)
A binned Dalitz plot analysis of B± → DK± decays, with D → K0S
+ −
and D → K0S
K+K−, is performed to measure the CP-violating observables x± and y±,
which are sensitive to the Cabibbo-Kobayashi-Maskawa angle
. The ...
Measurement of indirect CP asymmetries in D0 → K−K+ and D0 → π−π+ decays using semileptonic B decays
(Springer, 2015)
Time-dependent CP asymmetries in the decay rates of the singly Cabibbo-suppressed decays D0 → K−K+ and D0 → π−π+ are measured in pp collision data corresponding to an integrated luminosity of 3.0 fb−1 collected by the LHCb ...
Measurement of the χ b (3P) mass and of the relative rate of χ b1(1P) and χ b2(1P) production
