Speaker: Lingfeng Li 李凌风 (ICTP-AP)Time: 2:30PM, 12-4, 2025Location: Room 9409Abstract:In this talk, we discuss the Standard Model (SM) electroweak (EW) sector as a portal to the hidden sector, with EW bosons serving as mediators. We propose several UV complete models of the EW portal and explore their prospects in EW precision tests (EWPT). A rich phenomenology emerges when the hidden sector admits ...

The transverse polarization of Λ hyperons within unpolarized jets is encoded in the transverse-momentum-dependent (TMD) fragmentation function . In the vacuum environment, the QCD evolution of this TMD fragmentation function is governed by the Collins-Soper equation. However, in the presence of ...

:We examine the length scales usually associated with the applicability of hvdrodynamics as an efective theory in the ight of the observation of hydrodynamic behavior in small systems. We argue that the explanation of such behavior might reside in the requirement of local equivalence between fuctuations ...

Particle azimuthal anisotropies inside jets, defined within the momentum plane perpendicular to the jet axis, carry the information of the QCD cascade process for jet formation. In this work, we propose to measure the medium-induced modifications of the elliptic anisotropy inside jets in relativistic heavy-...

Fifty years have passed since the predictions of the existence of the Quark-Gluon Plasma, a high-temperature and high-density phase of matter, in which the colour charge of OCD becomes deconfined. I will recall some of major milestones in the history of the QGP, that led to the confirmation of ...
