Updated LHCb combination of the CKM angle $\gamma$ /LHCb Collaboration
The latest results of the CKM angle $\gamma$ combination are presented for the 2020 LHCb Implications Workshop. New and updated inputs from $B^+ \to Dh^+$ ($D\to h^+h^-$), $B^+ \to Dh^+$ ($D \to K^0_{\rm S} h^+h^-$), $B^+ \to Dh^+$ ($D \to K^0_{\rm S} K^+ \pi^-$), $B^+ \to D^*h^+$ ($D\to h^+h^-$), $B^0 \to D K^{*0}$ ($D\to h^+h^-$ and $D\to h^+\pi^-\pi^+\pi^-$) and $B^0_s \to D^\mp_s K^\pm \pi^\mp \pi^\pm$ ($D^+_s \to h^+ h^- \pi^+$) decays are included, where $h = K$ or $\pi$.

Analytic integration of soft and collinear radiation in factorised QCD cross sections at NNLO / Magnea, Lorenzo ; Pelliccioli, Giovanni ; Signorile-Signorile, Chiara ; Torrielli, Paolo ; Uccirati, Sandro
Within the framework of local analytic sector subtraction, we present the full analytic integration of double-real and real-virtual local infrared counterterms that enter NNLO QCD computations with any number of massless final-state partons. [...]

Combined Explanation of the $Z\to b\bar b$ Forward-Backward Asymmetry, the Cabibbo Angle Anomaly, $\tau\to\mu\nu\nu$ and $b\to s\ell^+\ell^-$ Data / Crivellin, Andreas ; Manzari, Claudio Andreas ; Alguero, Marcel ; Matias, Joaquim
In this article we propose a simple model which can provide a combined explanation of the $Z\to b\bar b$ forward-backward asymmetry, the Cabbibo Angle Anomaly (CAA), $\tau\to\mu\nu\nu$ and $b\to s\ell^+\ell^-$ data. [...]

Observation of a new $\Xi_b^0$ state / LHCb Collaboration
Using a proton-proton collision data sample collected by the LHCb experiment, corresponding to an integrated luminosity of 8.5~fb$^{-1}$, the observation of a new excited $\Xi_b^0$ resonance decaying to the $\Xi_b^-\pi^+$ final state is presented. [...]

Low-mass dielectron measurements in pp, p-Pb, and Pb-Pb collisions with ALICE at the LHC / Scheid, H. Sebastian
Dielectrons are an excellent probe for the QCD matter created in created in ultra-relativistic heavy-ion collisions, since they are emitted during the whole evolution of the collision and do not interact strongly with the medium. [...]
