(YSF) Search for additional neutral MSSM Higgs bosons in the di-tau final state at CMS / Spanring, Markus (Vienna, OAW) /CMS Collaboration
A search for aditional neutral Higgs bosons in the $\tau\tau$ final state is presented. The search is performed in the context of the minimal supersymmetric extension of the standard model (MSSM), using data from proton-proton collison collected with the CMS detector in 2016 at a center-of-mass energy of 13~TeV.

Testing the system size dependence of hydrodynamical expansion and thermal particle production with $\pi$, K, p, and $\phi$ in Xe-Xe and Pb-Pb collisions with ALICE / Bellini, F.
We present new results on transverse momentum spectra, integrated yields, and mean transverse momenta of pions, kaons, and protons, as well as of $\phi$-mesons for various centrality classes measured in Pb-Pb and Xe-Xe collisions at the LHC. [...]

Field integrals for the ATLAS tracking volume / Klyukhin, V.I. (Serpukhov, IHEP) ; Poppleton, A. (CERN) ; Schmitz, J. (Nikhef, Amsterdam)
The magnetic field integrals connected with the momentum resolution are calculated for the ATLAS inner tracking volume in a range of pseudorapidity $|\eta| < 3$ for the cases of `ideal' and inhomogeneous solenoid fields. [...]

The MESS of cosmological perturbations / Romano, Antonio Enea (CERN ; ICRA, Pescara) ; Pena, Sergio A. Vallejo (ICRA, Pescara)
We introduce two new effective quantities for the study of comoving curvature perturbations $\zeta$: the space dependent effective sound speed (SESS) and the momentum dependent effective sound speed (MESS) . [...]

Search for a charged Higgs boson decaying to charm and bottom quarks in proton-proton collisions at $\sqrt{s} = $ 8 TeV
A search for charged Higgs boson decaying to a charm and a bottom quark (${{\mathrm{H}^+} \to\mathrm{c}\mathrm{\bar{b}}} $) is performed using 19.7 fb$^{-1}$ of pp collision data at $\sqrt{s} = $ 8 TeV. [...]

Measurements of $\pi^{\pm}$, $K^{\pm}$ and proton yields from the surface of the T2K replica target for incoming 31 GeV/c protons with the NA61/SHINE spectrometer at the CERN SPS / Berns, L. ; Fiorentini, G.A. ; Friend, M. ; Hartz, M. ; Vladisavljevic, T. ; Yu, M.
Measurements of the $\pi^{\pm}$, $K^{\pm}$, and proton double differential yields emitted from the surface of the 90-cm-long carbon target (T2K replica) were performed for the incoming 31 GeV/c protons with the NA61/SHINE spectrometer at the CERN SPS using data collected during 2010 run. [...]

Rare decays at CMS / Piedra Gomez, Jonatan (Cantabria Inst. of Phys.) /CMS Collaboration
Searches for flavour changing neutral currents (FCNC) in events with top quarks and the Z or the Higgs boson are presented by the CMS Collaboration. These searches use proton-proton collision events taken by the CMS experiment at the Large Hadron Collider (LHC), built by the European Organization for Nuclear Research (CERN). Upper limits at $95\%$ confidence level are set on the branching fractions of ${\rm t \to qZ}$ and ${\rm t \to qH}$ decays. [...]

Precision Timing Calorimetry with the upgraded CMS Crystal ECAL / Ciriolo, Vincenzo (INFN, Milan Bicocca ; Milan Bicocca U.) /CMS Collaboration
Particle detectors with a timing resolution of order 10 ps can improve event reconstruction at high luminosity hadron colliders tremendously. The upgrade of the Compact Muon Solenoid (CMS) crystal electromagnetic calorimeter (ECAL), which will operate at the High Luminosity Large Hadron Collider (HL-LHC), will achieve a timing resolution of around 30 ps for high energy photons and electrons.

Observation of $\mathrm{t}\overline{\mathrm{t}}\mathrm{H}$ production at CMS / Salerno, Daniel Nicholas (Zurich U.) /CMS Collaboration
The observation of Higgs boson production in association with a top quark-antiquark pair is reported, based on a combined analysis of proton-proton collision data at center-of-mass energies of $\sqrt{s}=7$, 8 and 13 TeV, corresponding to integrated luminosities of up to 5.1, 19.7, and 35.9 fb${}^{-1}$, respectively. The data were collected with the CMS detector at the CERN LHC. [...]
