Measurement of CP observables in B0 -> D K*0 with D -> K+ K-
LHCb collaboration, R. Aaij, C. Abellan Beteta +625
The decay B0 -> D K*0 and the charge conjugate mode are studied using 1.0fb-1 of pp collision data collected by the LHCb experiment at sqrt(s) = 7TeV in 2011. The CP asymmetry betw…
Measurement of the forward energy flow in pp collisions at sqrt(s)=7 TeV
LHCb collaboration, R. Aaij, C. Abellan Beteta +628
The energy flow created in pp collisions at sqrt(s)=7 TeV is studied within the pseudorapidity range 1.9<eta<4.9 with data collected by the LHCb experiment. The measurements are pe…
First evidence for the decay Bs -> mu+ mu-
LHCb collaboration, R. Aaij, C. Abellan Beteta +617
A search for the rare decays Bs->mu+mu- and B0->mu+mu- is performed using data collected in 2011 and 2012 with the LHCb experiment at the Large Hadron Collider. The data samples co…
