  1. 98. Statistical combination of searches for the X(5568) state decaying into $B^0_s π ^±$

    Poster

    A statistical combination of the search results for the X(5568) resonance decaying into $𝐵^0_𝑠 π^{±}$ is reported, based on published results from the ATLAS, CMS, CDF and LHCb Collaborations.
    A narrow structure in the invariant mass distribution of $𝐵^0_𝑠 π^{±}$ has been observed by the D0 Collaboration with a mass value of 5568 MeV and interpreted as the first observation of a possible...

  2. 185. The study of the rare decays $B^{0}_s \rightarrow \mu^+\mu^-$ at $\sqrt{s}$ = 13 TeV with the ATLAS detector

    Poster

    The flavour-changing neutral currents of the rare decays $B^{0}_s \rightarrow \mu^+\mu^-$ provide a favourable environment to observe new physics. The study of these decays, using the data collected by the ATLAS detector, is presented. Their branching ratios are measured relative to the reference decay mode $B^{+/-} \rightarrow J/\psi K^{+/-}$, which is abundant and has a well-measured...

  4. 435. Discriminating new physics scenarios in $b\rightarrow s\,\mu^+\,\mu^-$ via transverse polarization asymmetry of $K^*$ in $B\rightarrow K^*\,\mu^+\,\mu^-$ decay

    Poster

    A global fit to current $b\rightarrow s\,l^+\,l^-$ data suggest several new physics solutions. Considering only one operator at a time and new physics in the muon sector, it has been shown that the new physics scenarios (I) $C_9^{\rm NP}<0$, (II) $C_{9}^{\rm NP} = -C_{10}^{\rm NP}$, (III) $C_9^{\rm NP} = -C_9^{\rm 'NP}$ can account for all data in this sector. In order to discriminate...

  5. 682. Improved determination of |Vus| with tau decays

    Poster

    We present improved determinations of |Vus| with tau decays relying on the HFLAV tau branching fractions global fit results. Precision improvements come from using recent resuts from BaBar and recent evaluations with lattice of the electromagnetic (e.m.) and strong isospin-breaking corrections to the π+→μ+ν[γ] and K+→μ+ν[γ] leptonic decay rates. A third determination of |Vus| has been added to...

  6. 1055. Untagged analysis of B → πlν̄ and first measurement of |Vub| at Belle II

    Poster

    A long standing discrepancy between the results of exclusive and inclusive measurements of the CKM matrix element |Vub| exists. The charmless semileptonic decay B → πlν̄ is one of the most accessible and powerful channels for determining |Vub| in exclusive modes at e+ e− B-factories. Using data from the Belle II experiment, a new precision measurement of |Vub| becomes possible. In preparation...
