Study of production of electrons from beauty-hadron decays in pp collisions at $\sqrt{s}$ = 13 TeV and Pb-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV with ALICE / Park, Jonghan (Inha U.) ; Kwon, Jiyeon (Inha U.) /ALICE
Heavy quarks, charm and beauty, are expected to be effective probes for the hot and dense medium (QGP) produced in high-energy heavy-ion collisions. They are produced in the early stage of the collision, almost exclusively in hard partonic scattering, and therefore they experience the full evolution of the QGP allowing to study the in-medium partonic energy-loss.

Measurement of azimuthal correlations of D mesons with charged particles in pp collisions at $\sqrt{s}$ = 13 TeV with ALICE at the LHC / Naik, Bharati (Indian Inst. Tech., Mumbai) /ALICE
The ALICE (A Large Ion Collider Experiment) detector at the LHC (Large Hadron Collider) is designed to study the properties of Quark-Gluon Plasma (QGP), a deconfined state of quarks and gluons produced in ultrarelativistic heavy ion collisions. The heavy quarks (charm and beauty) are produced in the initial stages of the collisions due to their large masses. [...]

Study of the differential Drell-Yan cross sections at 13 TeV with CMS / Pai, Dalmin (Seoul Natl. U. (main))
Studies of the differential Drell-Yan cross sections in the dilepton channel are presented. The analysis is based on data taken with the CMS detector at a proton-proton center of mass energy of 13 TeV. [...]

Search for the pair production of first generation scalar leptoquarks at $\sqrt{s}$ = 13 TeV / Bhat, Muzamil Ahmad (Tata Inst.) /CMS
The quark and lepton sectors of the standard model (SM) are strikingly similar in terms of the number of particles and generations. This hints at a fundamental symmetry existing between the two sectors. [...]

Update on the TowerJazz CMOS DMAPS development for the ATLAS ITk / Dachs, Florian (CERN ; TU Vienna) ; Sharma, Abhishek (U. Oxford (main)) ; Hiti, Bojan (Stefan Inst., Ljubljana) ; Solans Sanchez, Carlos (CERN) ; Marin Tobon, Cesar Augusto (CERN) ; Riegel, Christian (Bergische U., Wuppertal (main)) ; Schioppa, Enrico Junior (CERN) ; Pernegger, Heinz (U. Oxford (main)) ; Asensi Tortajada, Ignacio (U. Valencia (main) ; CSIC, Madrid) ; Berdalović, Ivan (CERN) et al.
The upgrade of the ATLAS tracking detector for the High-Luminosity Large Hadron Collider at CERN requires the development of novel radiation hard silicon sensor technologies. For the development of depleted CMOS sensors for ATLAS we combined small electrodes with minimal capacitance and advanced processing for fully depleted active sensor volume to achieve radiation hard CMOS sensors in line with ATLAS ITk specifications.

From CERN knowledge to society / Cirilli, Manuela (CERN)
CERN’s mission is the pursuit of knowledge through curiosity-driven research. The Laboratory was created to explore the fundamental particles and their interactions, with the goal of helping us to understand how the universe works. [...]

Experimental investigation of $\pi^+\pi^-$ and $K^+K^-$ atoms / Afanasyev, Leonid (Dubna, JINR) /DIRAC
The adapted DIRAC experiment at the CERN PS accelerator observed for the first time long-lived hydrogen-like $\pi^+\pi^-$ atoms, produced by protons hitting a beryllium target. A part of these atoms crossed the gap of 96 mm and got broken up in the 2.1 $\mu$m thick platinum foil. [...]

CMS muon reconstruction and identification performance of Run2 data / Jeon, Si Hyun (Seoul Natl. U. (main)) /CMS Collaboration
The Compact Muon Solenoid (CMS) detector is one of the 4 detectors at the CERN LHC to study the Standard Model (SM) and even searching for signatures of new physics produced in high-energy collisions in the LHC. As many of the signatures in both SM and new physics include muons, it is crucial to possess high performance of muon identification and reconstruction. [...]

Measurement of $t\bar{t}$ production cross sections in association with b jets and inclusive jets and their ratio using dilepton final states in pp collisions at $\sqrt{s}$=13 TeV / Hwang, Chanwook (Sungkyunkwan U.) /CMS Collaboration
The cross sections for the production of $t\bar{t}b\bar{b}$ and ${t\bar{t}jj}$ and their ratio $\sigma_{t\bar{t}b\bar{b}}/\sigma_{t\bar{t}jj}$ are measured using data corresponding to an integrated luminosity of 2.3 fb$^{-1}$ collected in pp collisions at $\sqrt{s}$=13 TeV with the CMS detector at the LHC. Events with two leptons (e or $\mu$) and at least four reconstructed jets, including at least two identified as b quark jets, in the final state are selected. [...]

Search for supersymmetric partners of the tau lepton with CMS / Babounikau, Illia (DESY) /CMS Collaboration
Searches for supersymmetry are presented that target direct and indirect stau pair production.The analyses exploit the final states with two taus of opposite charge and significant missing transverse momentum. The results are based on a data set of proton-proton collisions, recorded by the CMS experiment at a center-of-mass energy of 13 TeV and corresponding to an integrated luminosity of 36 $fb^{−1}$ .
