1063por Aiola, Salvatore“…A general agreement was found, confirming that we understand the general features of jet and heavy-flavor production in the framework of QCD. Another measurement was performed in Pb-Pb collisions at a center-of-mass energy per nucleon $\sqrt{s_{\rm NN}}=2.76$~TeV. …”

1067por D'Argent, Philippe“…The $B_s- \bar B_s$ oscillation frequency is measured from flavor-specific $B_s \to D_s^- \pi^+ \pi^+ \pi^-$ decays to be $\Delta m_s = (17.7651 \pm 0.0084 (\text{stat}) \pm 0.0058 (\text{syst})) \, \text{ps}^{-1}$, consistent with and significantly more precise than the current world-average value. …”

1068“…Several experiments revealed intriguing hints for lepton flavor universality (LFU) violating new physics (NP) in semi-leptonic $B$ meson decays, mainly in $b \to c \tau \nu$ and $b \to s \ell^+ \ell^-$ transitions at the $3-5\,\sigma$ level. …”

1076por Giacobbe, Benedetto“…Particular emphasis is devoted to the discussion of the modeling issues affecting the flavor-inclusive selection and of the ability of the experimental results obtained with the 𝑏-tag selection to discriminate among models implementing different flavor-number schemes to describe the initial state of the interaction.…”
