The High Luminosity-Large Hadron Collider (HL-LHC) will reach an approximate pile-up of 200
collisions per bunch crossing, ten times more than the current Large Hadron Collider. Beginning
operation in 2030, it will accumulate 3000 fb-1, increasing the chances of observing new processes
and allowing measurement of rare processes with higher precision. Moreover, the pile-up increase
means more...
Lepton Flavour Universality (LFU) is an accidental symmetry of the Standard Model (SM) which stablishes that all three lepton families have the same coupling to the electro-weak force carriers. The combination of recent LFU test results in b→clν transitions show a 4.2σ tension with the SM predictions, suggesting this may be the right direction to find New Physics. These results come from...
This poster presents the measurement of the inclusive cross-section for the single top t-channel process. This process has the highest cross section in the single top family and involves a special final state with a light jet in the forward region of the detector. The cross section is measured using data recorded by CMS in 2022 and 2023, with a total luminosity of 62 $fb^{-1}$ and a...
The ratio R32 of the three-jet to the two-jet inclusive differential cross sections is a well-established tool to study perturbative QCD. In this work, this observable is adapted to top-quark physics by considering the ratio of the $t\bar{t}$+jet to the $t\bar{t}$ cross sections as a function of different kinematic variables. Theoretical predictions are provided at next-to-leading order using...
The scale evolution of quark masses predicted by the Standard Model can be probed at collider experiments. Measurements at particle colliders can probe the scale evolution of quark masses predicted by the Standard Model in several ways. The experiments at LEP and SLD extracted $m_b(m_Z)$, that is the bottom-quark mass at the scale of the Z boson mass, with a precision of several hundred MeV...
