Jet suppression in high-energy heavy-ion collisions results from jet energy loss and transverse-momentum broadening during jet propagation through the quark-gluon plasma (QGP). The jet cone size ($R$) dependence of this suppression offers crucial insights into the energy loss mechanisms and QGP transport properties....

The parton structure of the nucleus at very low Bjorken-x, especially its gluon content, is largely unknow.  Measurements at small-x will not only provide experimental constrains for (nuclear) PDFs in a region of phasespace where experimental data is scarce, but will also enable ...

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 ...

Statistical physics is a fundamental discipline that investigates the relationship between microscopic behaviors and collective macroscopic properties in many-particle systems. Its theoretical origins can be traced back to the ensemble theory established by the American physicist J. Willard Gibbs....

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 ...
