Characterization of nuclear breakup as a function of hard-scattering kinematics using dijets measured by ATLAS in $p$ +Pb collisions
This Letter analyzes the sensitivity of event geometry estimators to the initial-state kinematics of hard scattering in proton-lead collisions. [...]

Search for rare muonic B decays at CMS / Szlezak, Klara Emilia (Warsaw U.) /CMS Collaboration
In this paper, we present the search for three highly suppressed Standard Model processes at the CMS experiment:

B^{0} \to μ^{+} μ^{-}

$B^{0} \to \mu^+ \mu^-$ ,

B_{s}^{0} \to μ^{+} μ^{-}

$B_{s}^{0} \to \mu^+ \mu^-$ , and

B_{s}^{0} \to μ^{+} μ^{-} γ

$B_{s}^{0} \to \mu^+ \mu^- \gamma$ . The latest and most precise results to date are presented for the first two decays, while the feasibility and experimental strategy for the third, yet unobserved at CMS, are discussed. [...]
