Beauty and charm production in pp collisions via D-meson measurements with ALICE
/ Catalano, Fabio (speaker) (Politecnico e INFN Torino (IT))
Measurements of the production of hadrons containing charm or beauty quarks in proton-proton collisions provide an important test of quantum chromodynamics calculations. They also set the reference for the respective measurements in heavy-ion collisions, where the formation and properties of the quark-gluon plasma are investigated.
The excellent particle identification, track and decay-vertex reconstruction capabilities of the ALICE experiment, together with machine-learning techniques for multi-class classification, are exploited to separate the signal of non-prompt D mesons (produced in beauty-hadron decays) from that of prompt D mesons (produced in the charm-quark fragmentation) and the combinatorial background [...]

The Future of Fundamental Physics
/ Dijkgraaf, Robbert (speaker) (Director and Leon Levy Professor of the Institute for Advanced Study, Princeton, New Jersey (USA))
The reports of the death of physics are greatly exaggerated. Instead, I would argue, we are living in a golden era and the best is yet to come [...]

New results on theoretically clean observables in rare B-meson decays from LHCb
/ Petridis, Konstantinos (speaker) (University of Bristol (GB)) ; Santimaria, Marco (speaker) (INFN e Laboratori Nazionali di Frascati (IT))
Over the past decade, measurements involving the flavour changing neutral current transition 𝑏→𝑠ℓ+ℓ− have shown tantalising tensions with Standard Model (SM) predictions. However, our current understanding of the hadronic uncertainties in these predictions potentially hinders our ability to interpret these results as physics beyond the SM [...]

Recent results on Vector Boson plus jet production from CMS
/ Nguyen, Duong Hai (speaker) (The State University of New York SUNY (US))
Vector boson production accompanied by light-jets, or heavy-flavor jets are essential processes to test different theoretical predictions and represents important backgrounds to other standard model or beyond the standard model processes. In this talk, recent measurements of the differential cross sections of Z + jets and γ + jets production as a function of the boson transverse momentum and other observables will be presented [...]
