 Recent results on heavy flavour in small and large systems from ALICE / Huang, Chun-Lu /ALICE Collaboration Heavy-flavour hadrons, containing open or hidden charm and beauty flavours, are considered as hard probes of the quark-gluon plasma (QGP), which is a hot and dense phase state of quantum chromodynamics (QCD) matter. Production of heavy flavours involves large momentum transfer processes during collisions. [...] arXiv:2010.12469.- 2020-10-23 - Published in : PoS: LHCP2020 (2020) , pp. 036 Fulltext: PDF;

 PPS results and prospects from CMS/TOTEM collaborations / Royon, C. (Kansas U.) We describe the most recent results from the Proton Precision Spectrometer from the CMS and TOTEM collaborations, namely the first observation of exclusive di-lepton production at high mass at the LHC, and the prospects concerning the sensitivity to quartic anomalous couplings... arXiv:2007.00440.- 2020-06-26 - 8 p. - Published in : (2020) , pp. 139-146 In : Proceedings: Workshop on Forward Physics and QCD at the LHC, the Future Electron Ion Collider, and Cosmic Ray Physics, Guanajuato, Mexico, 18 - 21 Nov 2019, pp.139-146

 Recent results from the TOTEM collaboration at the LHC / Royon, C. (Kansas U.) We describe the most recent results from the TOTEM collaboration at the LHC, namely the elastic cross section measurements at a center-of-mass on 2.76, 7, 8 and 13 TeV. No structure or resonance is observed at high $t$ at high center-of-mass energies.

 A Forward Multiparticle Spectrometer for the LHC: Hadron spectra and Long-lived particle search / Albrow, Michael G. (Fermilab) I describe a possible Forward Multiparticle Spectrometer (FMS) that could be installed downstream of the superconducting recombination dipole D1 in Run 4, from z = 96 m - 126 m to measure multi-TeV hadron spectra in low luminosity p + p collisions at Rt(s) = 14 TeV, as well as p + O and O + O collisions as relevant for cosmic ray showers. Light antinuclei and charmed hadrons at high Feynman xF can be measured, both of importance for astrophysics.

 Through the looking-glass with ALICE into the quark-gluon plasma: A new test for hadronic interaction models used in air shower simulations / Anchordoqui, Luis A. (Lehman Coll. ; CUNY, Graduate School - U. Ctr. ; Amer. Museum Natural Hist.) ; García Canal, Carlos (La Plata U.) ; Sciutto, Sergio J. (La Plata U.) ; Soriano, Jorge F. (Lehman Coll. ; CUNY, Graduate School - U. Ctr.) Recently, the ALICE Collaboration reported an enhancement of the yield ratio of strange and multi-strange hadrons to charged pions as a function of multiplicity at mid-rapidity in proton-proton, proton-lead, lead-lead, and xenon-xenon scattering. ALICE observations provide a strong indication that a quark-gluon plasma is partly formed in high multiplicity events of both small and large colliding systems.

 The High Frequency Longitudinal and Transverse Pick-Ups in the CERN SPS Accelerator / Linnecar, T. P. R. (CERN) The different applications and consequent specifications for longitudinal and transverse high frequency pick-ups in the CERN SPS have led to the use of three separate types of pick-up; they are the electrostatic, the wall current and the directional coupler pick-up. The high frequency longitudinal pick-ups are protected from propagating waveguide modes by traps.

 CMS RPC Activities During LHC LS-2 / CMS Collaboration The second LHC long shutdown period (LS2) is an important opportunity for the CMS Resistive Plate Chambers (RPC) to complete their consolidation and upgrade projects. The consolidation includes detector maintenance for gas tightness, HV (high voltage), LV (low voltage) and slow control operation.

 Energy and multiplicity dependence of strange and non-strange particle production in proton-proton collisions at the LHC with ALICE / Fionda, Fiorella Maria Celeste (Bergen U.) /ALICE Collaboration ,The study of energy and multiplicity dependence of hadron production in proton-proton collisions provides a powerful tool to understand similarities and differences between small and large colliding systems. In this work we present mid-rapidity measurements of the pT spectra and yields of identified hadrons, namely pions, kaons, protons, $K_{s}^{0}$, $\Lambda$, $\Xi$  and $\Omega$ in pp collisions at  $\sqrt{s}$ = 7 and 13 TeV.

 $J/\psi$ production in proton-lead collisions at 8 TeV with the LHCb detector / Okhrimenko, Oleksandr (Kiev, INR) /LHCb Collaboration The production of J/ψ mesons is studied in proton-lead collisions at a centre-of-mass energy per nucleon pair $\sqrt{s_{NN}}$ = 8.16 TeV with the LHCb detector. The double differential cross-sections of prompt and nonprompt J/ψ production are measured as functions of the J/ψ transverse momentum and rapidity.

 Estimation of the isothermal compressibility from event-by-event multiplicity fluctuation studies / Mukherjee, Maitreyee (Bose Inst., Kolkata ; CAPSS, Kolkata) ; Basu, Sumit (Wayne State U.) ; Thakur, Sanchari (Calcutta, VECC) ; Adhya, Souvik P (Calcutta, VECC) ; Chatterjee, Arghya (Calcutta, VECC) ; Chatterjee, Sandeep (AGH-UST, Cracow) ; Nayak, Tapan K (Calcutta, VECC ; CERN) The first estimation of the isothermal compressibility ($_{k_T}$) of matter is presented for a wide range of collision energies from $\sqrt{s_{NN}}$   = 7.7 GeV to 2.76 TeV. $_{k_T}$ is estimated with the help of event-byevent charged particle multiplicity fluctuations from experiment.
