Using a data sample corresponding to an integrated luminosity of 0:35 fb 1 collected by LHCb in 2011, we report the first evidence of CP violation in the decays of Bs mesons to K pairs, ACPðBs ! K Þ 1⁄4 0:27 0:08ðstatÞ 0:02ðsystÞ, with a significance of 3:3 . Furthermore, we report the most precise measurement of CP violation in the decays of B mesons to K pairs, ACPðB !

We investigate the static potential in the confinement phase of the SU(2) Higgs model on the lattice, where this model is expected to have properties similar to QCD. We observe that Wilson loops are inadequate to determine the potential at large distances, where the formation of two color-neutral mesons is expected. Introducing smeared fields and a suitable matrix correlation function, we are a...

Abstract Introduction With the delay of reproductive age, disorders related to advanced age have gradually attracted widespread attention. Studies shown that decline in male fertility due aging is manifested as a decrease semen parameters and spermatogenetic cells histologically. O-GlcNAc (O-acetylglucosamine) glycosylation post-translational modification exists widely cells. The level UDP-GlcN...
