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 ...

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 ...

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 ...

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 ...
