Quarkonium Polarization in Medium from Open Quantum Systems and Chromomagnetic Correlators
Di-Lun Yang, Xiaojun Yao
We study the spin-dependent in-medium dynamics of quarkonia by using the potential nonrelativistic QCD (pNRQCD) and the open quantum system framework. We consider the pNRQCD Lagran…
QCD sum rules with spectral densities solved in inverse problems
Hsiang-nan Li, Hiroyuki Umeeda
We construct QCD sum rules for nonperturbative studies without assuming the quark-hadron duality for the spectral density at low energy on the hadron side. Instead, both resonance…
Next-to-leading-logarithm resummation for decays
Xin Liu, Hsiang-nan Li, Zhen-Jun Xiao
We derive the resummation for a transverse-momentum-dependent charmonium wave function, which involves the bottom quark mass , the charm quark mass , and the charm…
An explanation for the muon and electron anomalies and dark matter
Kai-Feng Chen, Cheng-Wei Chiang, Kei Yagyu
We propose simple models with a flavor-dependent global and a discrete symmetries to explain the anomalies in the measured anomalous magnetic dipole mome…
Triangle Singularity as the Origin of the
G. D. Alexeev, M. G. Alexeev, A. Amoroso +194
The COMPASS experiment recently discovered a new isovector resonance-like signal with axial-vector quantum numbers, the , decaying to . With a mass too close…
Constraining sterile neutrinos by core-collapse supernovae with multiple detectors
Jian Tang, TseChun Wang, Meng-Ru Wu
The eV-scale sterile neutrino has been proposed to explain some anomalous results in experiments, \textit{such as} the deficit of reactor neutrino fluxes and the excess of $\barν_μ…
