Abstract
CP violation in Bs0–B¯s0 oscillations is expected at the 10−5 level in the Standard Model but could be enhanced by New Physics. Using Bs0→Ds−ℓ+νℓ decays, LHCb has recently reported the new result (0.39±0.33)×10−2 of the corresponding observable asls. We point out that other current B decay data imply asls=(0.004±0.075)×10−2. In view of this strong constraint, we propose to use Bs0→Ds−ℓ+νℓ and similar flavor-specific decays as a new tool to determine both the production asymmetry between Bs0 and B¯s0 mesons, and the CP asymmetry in the subsequent Ds± decays. The former serves as input for analyses of CP violation in Bs0 channels, with significant room for improvement, while the latter offers an exciting laboratory for New Physics.
Highlights
Studies of CP violation provide interesting tests of the Standard Model (SM)of particle physics, where decays of neutral0 s mesons play a key role at the Large Hadron Collider (LHC) [1]
We are moving towards impressive new frontiers in highprecision studies of CP violation
The global agreement of the current data with the Standard Model raises the question of how much space is left for New Physics
Summary
0 s mesons play a key role at the Large Hadron Collider (LHC) [1] These particles show 0 s mixing, which. B-meson decays was obtained, in accordance with the SM In view of this progress, the question arises how much space for NP effects in assl is left by the data. This important issue, which can be raised for many flavor-physics observables, is the key motivation of the following discussion. – in a model-independent way – at the 10−4 level In view of this strong constraint, we propose a new method to uCBtP0si–lvizBioe0slaflptarivooondru-icsntpieDocn±sifiadcseyBcma0s ymds,eetwcrayhyisac.nhIdtisaoltplionewnyssinathtneheedweStMaevrembnuiunteamttiaooynebxoepf letohnreehanced through NP effects.
