Search for a new resonance decaying into two spin-0 bosons in a final state with two photons and two bottom quarks in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
A search for a new boson X is presented using CERN LHC proton-proton collision data collected by the CMS experiment at $ \sqrt{s} = $ 13 TeV in 2016-2018, and corresponding to an integrated luminosity of 138 fb$ ^{-1} $. [...]

Central exclusive production in CMS+TOTEM / Sikler, Ferenc (Budapest, RMKI) /CMS and TOTEM Collaborations
The central exclusive production of charged hadron pairs in pp collisions at a centre-of-mass energy of 13 TeV is examined, based on data collected in a special high-$\beta^*$ run of the LHC. Events are selected by requiring both scattered protons detected in the TOTEM Roman pots, exactly two oppositely charged identified particles in the CMS silicon tracker, and the energy-momentum balance of these four particles. [...]

Search for Higgs boson pair production in the bbWW* final state in proton-proton collisions with the full Run2 CMS data / Nandan, Saswati (NICPB, Tallinn) /CMS Collaboration
The results of a search for Higgs boson pair ($HH$) production in the final state $bbWW^*$ have been presented. The analysis is based on data recorded at a center of mass energy of 13 TeV by the CMS detector during LHC Run 2. [...]

Vector boson production in CMS / Tarricone, Cristiano (INFN, Turin ; Turin U.) /CMS Collaboration
This talk reviews recent measurements of single boson and multiboson production, including vector boson scattering processes, using CMS data. Inclusive and differential cross sections are measured using several kinematic observables, and constraints are placed on possible BSM contributions via the use of effective field theory techniques..

Toward Ten-Minute Turnaround in CMS Data Analysis The View from Notre Dame / Lawrence, John (Notre Dame U.) /CMS Collaboration
Effective analysis computing requires rapid turnaround times in order to enable frequent iteration, adjustment, and exploration, leading to discovery. An informal goal of reducing 10TB of experimental data in about ten minutes using campus-scale computing infrastructure is an achievable goal, just considering raw hardware capability. [...]

Rare decays at CMS / Guzzi, Luca (INFN, Milan Bicocca) /CMS Collaboration
The latest CMS results on the search for the neutrino-less $\tau^{\pm}\to\mu^{\pm}\mu^{\pm}\mu^{\mp}$ decay, the first observation of the $\eta\to\mu^+\mu^-\mu^+\mu^-$ decay, the measurement of the $B^0_s\to\mu^+\mu^-$ branching fraction, the measurement of the $B^0_s$ lifetime, the search for the $B^0\to\mu^+\mu^-$ decay, and the measurement of the angular observables of the $B^0\to K^{*0}\mu^+\mu^-$ decay are presented. The results are based on data collected in proton-proton collisions at the centre of mass energy of 8 TeV and 13 TeV..
