Measurement of the CKM angle γ from a combination of B±→Dh± analyses
(, , 2013-10-07)
A combination of three LHCb measurements of the CKM angle gamma is presented. The decays B-+/- -> DK +/- and B-+/- -> D pi(+/-) are used, where D denotes an admixture of D-0 and (D) over bar (0) mesons, ...
Measurement of sigma(pp -> b anti-b X) at sqrt(s)=7 TeV in the forward region
(, , 2010)
Decays of b hadrons into final states containing a Dº meson and a muon are used to measure the bb production cross-section in proton–proton collisions at a centre-of-mass energy of 7 TeV at the LHC. In ...
