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 ...

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 ...

The Higgs mechanism is responsible for elementary particle mass generation in the Standard Model of particle physics. While ATLAS and CMS experiments have confrmed its role in giving mass to the weak bosons and 3rd generation charged fermions, whether Higgs mechanism also provides mass for ...
