Speaker: 徐凌霄 博士, (the Abdus Salam International Centre for Theoretical Physics)Time: 2025年12月29日·周一下午 14:00Location: 9号楼9409会议室Abstract: Motivated by recent advances in the generalization of global symmetries in quantum fieldtheory, we introduce a class of selection rules originating from non-invertible fusion algebras rather thanconventional group laws, which we refer to as non-invertible ...

Exploring heavy vector mesons of the J/ψ and Υ(1S) is crucial for understanding the quark gluon plasma (QGP) formed in heavy ion collisions. The influences of rotational effect on the properties of the J/ψ and the Υ(1S) are investigated by incorporating rotation medium into the holographic QCD. It is ...

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 ...
