Hybrid Message Passing-Based Detectors for Uplink Grant-Free NOMA Systems
Yi Song, Yiwen Zhu, Kun Chen-Hu +3
This paper studies improving the detector performance which considers the activity state (AS) temporal correlation of the user equipments (UEs) in the time domain under the uplink…
Perturbative QCD Analysis of Near Threshold Heavy Quarkonium Photoproduction at Large Momentum Transfer
Peng Sun, Xuan-Bo Tong, Feng Yuan
We apply perturbative QCD to investigate the near threshold heavy quarkonium photoproduction at large momentum transfer. From an explicit calculation, we show that the conventional…
UV divergence of the quasi-PDF operator under the lattice regularization
Yikai Huo, Peng Sun
Even since the "quasi" parton distribution function (PDF) was proposed under the large-momentum effective theory (LaMET) framework, its renormalization under the lattice regulariza…
Impact of Dynamical Charm Quark and Mixed Action Effect on Light Hadron Masses and Decay Constants
Tong-Wei Lin, Zun-Xian Zhang, Mengchu Cai +8
We investigate the impact of including a dynamical charm quark on the properties of light hadrons. Our study compares the calculations performed on 2+1+1 flavor (HISQ fermion) ense…
Exponential Decay of Lebesgue Numbers
Peng Sun
We study the exponential rate of decay of Lebesgue numbers of open covers in topological dynamical systems. We show that topological entropy is bounded by this rate multiplied by d…
First Extraction of Transverse Momentum Dependent Helicity Distributions
Ke Yang, Tianbo Liu, Peng Sun +2
We report on the first global analysis of transverse momentum dependent helicity distributions of the proton. The analysis is performed at next-to-leading order with the evolution…
