Status of the Fast Interaction Trigger for ALICE Upgrade / Slupecki, Maciej (Helsinki Inst. of Phys.) /ALICE Collaboration
The Fast Interaction Trigger (FIT) denotes a set of three new detectors being part of the upgrade of ALICE in preparation for Run 3 of the LHC at CERN. To fulfill its physics objectives, ALICE aims to collect in Run 3 all minimum-bias data at the target interaction rate of 50 kHz for Pb-Pb and up to 1 MHz for pp collisions. [...]

Production studies of $D$ and $B$ mesons at CMS / Mariani, Valentina (INFN, Perugia) /CMS Collaboration
The large amount of data accumulated by the CMS experiment during the Run 2 of LHC offers robust probes for testing the Standard Model and potentially reaching beyond it. In this report the new CMS measurements of prompt $D^{*+}$, $D^+$ and $D^0$ production cross sections at 13 TeV are presented, together with novel studies of the production of excited $B_c$ states carried out with full Run 2 data..

Highlights from the ALICE collaboration / Dobrigkeit Chinellato, David  (Campinas State U.) /ALICE Collaboration
Significant advances in heavy-ion physics have come about as almost ten years have passed since the beginning of the heavy-ion programme at the LHC. In thisdocument, we review some key results from the ALICE collaboration on a variety of topics, from properties of the quark-gluon plasma (QGP) to basic QCD, and discuss how theseset the stage for further measurements in the next decade..

Timepix3 as solid-state time-projection chamber in particle and nuclear physics / MOEDAL Collaboration
Timepix3 devices are hybrid pixel detectors developed within the Medipix3 collaboration at CERN providing a simultaneous measurement of energy (ToT) and time of arrival (ToA) in each of its 256$\times$256 pixels (pixel pitch: 55 µm). The timestamp resolution below 2 ns allows a measurement of charge carrier drift times, so that particle trajectories can be reconstructed in 3D on a microscopic level ($z$-resolution: 30-60 µm).

Searching for supersymmetric partners of top quarks at the CMS experiment / Bhattacharya, Soham (Tata Inst.) /CMS Collaboration
The newest results for classic searches for the pair-production of supersymmetric top partners in final states with and without leptons with the CMS detector are presented. The analysis strategies are developed to cover different scenarios of heavy top squarks as well as those with top squark mass close to the Standard Model top quarks. [...]

Rare decays of $\Lambda_b^0$, $B_c^+$, and other $b$-hadrons at LHCb / Lupato, Anna (Manchester U.) /LHCb Collaboration
Rare $b$-hadron decays are sensitive probes of New Physics through the study of branching fractions, angular observables and CP asymmetries among others. Moreover, the LHCb experiment has the opportunity to study rare decays of heavy b-quark hadrons such as $\Lambda_b$ baryons, which cannot be explored at the B factories. [...]

Track-based muon system alignment of the CMS detector / Kim, Hyunyong (Texas A-M) /CMS Collaboration
The alignment of the CMS muon detector is critical to maintaining accurate position determination of muon hits, thereby affecting momentum resolution and the sensitivity of physics analyses involving muons in the final state. Muon track data from both the muon system and the inner tracker is used to perform a multidimensional fit on the misalignment degrees of freedom. [...]

Precision calorimetry at high luminosity: the CMS electromagnetic calorimeter from the LHC Run 2 to the HL-LHC / Soldi, Dario (INFN, Turin) /CMS Collaboration
The CMS experiment at the LHC is equipped with a high granularity lead tungstate crystal electromagnetic calorimeter (ECAL) offering an excellent energy resolution. The ECAL was crucial in the discovery and subsequent characterization of the Higgs boson, particularly in the two photon and two Z boson decay channels. [...]

The Early Career, Gender & Diversity at LHCb / Smith, Eluned (RWTH Aachen U.) /LHCb Collaboration
LHCb is a collaboration of over 1300 members from 83 institutions based in 19 countries, and representing many more nationalities. We aim to work together on experimental high energy physics, and to do so in the best and most collaborative conditions. [...]

Search for new physics in $b\to s\ell^+ \ell^-$ transitions at CMS / Boletti, Alessio (LIP) /CMS Collaboration
The flavour-changing neutral current decays are interesting probes for new physics searches. The angular distributions of the $\mathrm{B}^+ \to \mathrm{K}^{*+} \mu^ +\mu^-$ decay is studied using a sample of proton-proton collisions at $\sqrt{s} = 8~\mathrm{TeV}$ collected with the CMS detector at the LHC, corresponding to an integrated luminosity of $20.5~\mathrm{fb}^{-1}$.
