Recent ALICE results on ultra-peripheral collisions / Horak, David (CERN) /ALICE
The LHC is not only the most powerful collider for proton-proton and heavy-ion collisions, but it is also the most powerful source of photon collisions, because the protons and ions in the accelerator carry an electromagnetic field, which can be viewed as a flux of quasi-real photons. The photon-nucleus and photon-proton processes can be studied in ultra-peripheral collisions and offer an unique opportunity to study fundamental interactions in QED and QCD providing for example experimental data to search for saturation and shadowing effects.

Particle production as a function of multiplicity in pp collisions with ALICE / Jahnke, Christiane (Sao Paulo U.) /ALICE
The study of particle production in high-multiplicity pp collisions has revealed unexpected collective effects. In order to investigate these features, particle yields as a function of event activity are measured by ALICE. [...]

CP violation in beauty with LHCb / Cruz Torres, Melissa Maria (Honduras U.) /LHCb
The study and search for new sources of $CP$ violation in the beauty sector provide not only a better understanding of the phenomenon itself and thus of the matter-antimatter asymmetry in the universe, but to a better understanding of the rich dynamic present in the hadronic environment. Several analyses performed by the LHCb experiment that gather new insights into $CP$ violation effects in non-leptonic $b$-hadron decays are presented in this document..

$CP$ violation in charm with LHCb / Hilton, Martha (Manchester U.) /LHCb
Measurements of charge-parity ($CP$) violation and mixing in charm allow tests of the Standard Model and can potentially probe physics beyond the Standard Model. The violation of $CP$ symmetry has been well established in the kaon and beauty sectors and was first observed in charm at the LHCb experiment in 2019. [...]

Heavy-flavour jet measurements with ALICE / Mazzilli, Marianna (Bari U. ; INFN, Bari) /ALICE
Heavy-flavour quarks, due to their large masses, are produced in the early stages of the relativistic hadronic collisions via hard scattering processes. Therefore, they are ideal probes to investigate the properties of the Quark-Gluon Plasma (QGP) produced in ultra-relativistic heavy-ion collisions, since they experience the full system evolution.

Searches for hadronic resonances in CMS / Yu, David Ren-Hwa (Brown U.) /CMS
New particles decaying to jet pairs, predicted by many theories of physics beyond the Standard Model, could be discovered at the Large Hadron Collider as resonances in the dijet invariant mass spectrum. Three searches for dijet resonances by the CMS Collaboration are presented, which employ several novel techniques to probe a wide range of resonance masses. [...]
