Heavy ion physics in ATLAS and CMS / Dyndal, M (AGH-UST, Cracow) /CMS Collaboration ; ATLAS Collaboration
An overview of the latest heavy-ion measurements with the ATLAS and CMS detectors at the LHC, utilizing the high statistics 5.02 TeV Pb+Pb data collected in 2015 and 2018, is given. These include multiple measurements of jet production and structure, which probe the dynamics of the hot and dense medium (quark-gluon plasma) formed in relativistic nucleus-nucleus collisions; measurements of quarkonia and heavy flavor production to probe the medium properties; and various measurements of ultra-peripheral collision processes..

Accelerating structures for the FCC-ee pre-injector complex: RF design, optimization, and performance analysis / Kurtulus, Adnan (CERN) ; Grudiev, Alexej (CERN) ; Latina, Andrea (CERN) ; Raguin, Jean-Yves (Ecole Polytechnique, Lausanne) ; Craievich, Paolo (Ecole Polytechnique, Lausanne) ; Bettoni, Simona (Ecole Polytechnique, Lausanne)
The Future Circular Collider electron-positron (FCC-ee) pre-injector complex demands high-performance RF accelerating structures to achieve reliable and efficient acceleration of beams up to 20 GeV. In this study, we describe an analytical approach to RF design for the traveling-wave (TW) structures including a pulse compression system to meet the rigorous specifications of the FCC-ee pre-injector complex.

The gravitational wave and short gamma-ray burst GW170817/SHB170817A / De Rujula, Alvaro (CERN ; Madrid, IFT)
This event, so far unique, beautifully confirmed the standard views on the gravitational waves produced by a merger of two neutron stars, but its electromagnetic multi-wavelenth observations disagreed with the numerous initial versions of the “standard fireball model(s)” of gamma ray bursts. Contrariwise, they provided strong evidence in favour of the “cannonball” model. [...]

Rare decays and tests of lepton universality at LHCb / Lisovskyi, V (Dortmund U.) /LHCb Collaboration
Recent studies on the semileptonic decays of heavy-quark hadrons at the LHCb experiment are presented. The excellent LHCb physics reach allows to study the meson and baryon decays, probe very rare transitions, and perform tests of lepton universality..

Search for CP violation in $t \bar{t} H$ and $tH$ production in multilepton channels at $\sqrt{s}$ = 13 TeV / Ramon Alvarez, C (Oviedo U.) /CMS Collaboration
We measure the CP structure of the Yukawa interaction between the Higgs boson (H) and the top quark in a data sample enriched in t$\bar{\mathrm{t}}$H and tH associated production. Data corresponding to an integrated luminosity of 138 fb$^{-1}$ collected in proton-proton collisions at $\sqrt{s}$ = 13TeV by the CMS experiment at the CERN LHC is used. [...]

Classical and exotic spectroscopy at LHCb / Marangotto, Daniele (Milan U. ; INFN, Milan) /LHCb Collaboration
The latest results on classical and exotic spectroscopy obtained by the LHCb Collaboration studying proton-proton collisions are presented. These include studies related to both conventional states, namely mesons and baryons, and exotic ones, notably tetra and pentaquark structures. [...]
