Obtaining precise theoretical predictions for both production and decay processes of heavy new particles is of great importance to constrain the allowed parameter space of BSM models and to properly assess the sensitivity for discoveries and for discriminating between different possible BSM scenarios.In this context, it is well known that large logarithmic corrections can appear in the presence of widely separated mass scales. In this talk, I will point out the existence of possible large, Sudakov-like, logarithms in external-leg corrections of heavy scalars. [...]

The inhomogeneous six-vertex model is a multi-parametric integrable 2D statistical system. With the anisotropy parameter |q|=1, the model is critical and is expected to exhibit a variety of interesting universal behaviour. [...]

The foreseen Large Hadron Collider upgrade is expected to deliver an integrated luminosity that is one order of magnitude larger after 2027. Rare processes and new phenomena may be observed in this high luminosity era. [...]

Astronomical observations provide strong evidence that a large proportion of the matter in the universe is “Dark Matter" (DM), which is currently not included in the Standard Model (SM) of particle physics. Furthermore, many cosmological models suggest Dark Matter should couple to the SM around the 100 GeV scale, and hence may be produced at the LHC, appearing as missing transverse momentum. [...]

The top quark, the most massive member of the standard model, is unique in that it is the only known fermion with a Yukawa coupling of order one. In addition, its short lifetime provides us with the only opportunity to study a quark prior to hadronization. [...]

The high luminosity LHC Upgrade will increase the instantaneous lu- minosity by a factor of five. The CMS detector will be upgraded in the so called Phase-2 Upgrade in order to meet the new requirements, among others the level of radiation tolerance and coping with larger pileup and thus higher data rates, as well as to add triggering capa- bilities.

An extended Higgs sector is well motivated in several Beyond the Standard Model theories. A vast set of models containing two Higgs doublets plus one additional Higgs singlet complex field (2HD+1S) are consistent with SM measurements, constraints from searches for additional Higgs bosons and supersymmetry, as well as with the measured properties of the H(125) boson.
