Towards a full description of MeV dark matter decoupling: a self-consistent determination of relic abundance and $N_{\rm eff}$ / Chu, Xiaoyong (Vienna, OAW) ; Kuo, Jui-Lin (UC, Irvine) ; Pradler, Josef (Vienna, OAW ; CERN)
Thermal dark matter at the MeV mass-scale has its abundance set during the highly non-trivial epochs of neutrino decoupling and electron annihilation. [...]

Large Field Distances from EFT strings / Lanza, Stefano (Utrecht U.) ; Marchesano, Fernando (Madrid, IFT) ; Martucci, Luca (Padua U. ; INFN, Padua) ; Valenzuela, Irene (Madrid, IFT ; Madrid, Autonoma U. ; CERN)
In any consistent effective field theory of quantum gravity limits of infinite field distance are expected to lead to the EFT breakdown due to the appearance of an infinite tower of light states, as predicted by the Distance Conjecture. [...]

Recent CMS heavy flavor physics results / Simone, Federica Maria (INFN, Bari ; Bari U.) /CMS Collaboration
In this paper, recent results in the B-physics field achieved using proton-proton collision data at $\sqrt{s}=8$ TeV and $13$ TeV collected by CMS are presented. They include the angular analysis of the decay $\mathrm{B^{+}}\to \mathrm{K}^{*+} \mu^{+} \mu^{-}$ with Run 1 data, new measurements of D and B mesons production cross sections and CP violation studies using ${B}_s^{0}$ decays with Run 2 data.

Performance monitoring of the GE1/1 Triple-GEM detectors for the CMS Muon System / Milella, Gabriele (DESY) ; Simone, Federica Maria (INFN, Bari ; Bari U.) /CMS Collaboration
The muon system of the CMS experiment has been instrumented with two wheels of triple-GEM detectors in order to ensure redundancy in the pseudo-rapidity region 1.55-2.18 so keeping the trigger rate at an acceptable level while not compromising the CMS physics potential in Run 3 of the LHC.The station, named GE1/1, provides two additional muon hit measurements which will improve the muon tracking and triggering performance in combination with the existing CSC detectors.As the commissioning phase of the detector is ongoing, prompt assessment of the muon detection performance is crucial for adjusting the operating parameters of the detector and its electronics. This contribution will present a set of analysis tools developed for the detector performance monitoring based on tools common to all the CMS muon subdetectors. [...]
