We introduce SEA-PINN, a novel architecture that incorporates a Squeeze-Excitation-like attention mechanism into physics-informed neural networks to dynamically recalibrate the importance of neurons across layers. A key feature of SEA-PINN is its highly stable initialization. On 17 out of 20 benchmark problems,...

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....

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 ...

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-...
