Angularity in Higgs boson decays via H→gg at NNLL'accuracy
《Chinese Physics C》2025年第2期60-80,共21页Jiawei Zhu Yujin Song Jun Gao Daekyoung Kang Tanmay Maji 
Supported by the National Key Research and Development Program of China(2020YFA0406301);the National Natural Science Foundation of China(12150610461);Jun Gao Sponsored by the National Natural Science Foundation of China(12275173,11835005);Tanmay Maji Supported by the Science and Engineering Research Board(SERB)through the SRG(Start-up Research Grant)of File(SRG/2023/001093)。
We present improved predictions of a class of event-shape distributions called angularity for a contribution from an effective operator in Higgs hadronic decay that suffers from large perturbative uncertainties.In the...

Scalar-pseudoscalar pair production at the Large Hadron Collider at NLO+NLL accuracy in QCD
《Chinese Physics C》2021年第12期8-21,共14页He-Yi Li Ren-You Zhang Yu Zhang Wen-Gan Ma Ming-Ming Long Shu-Xiang Li 
Supported in part by the National Natural Science Foundation of China(11775211,12061141005,11805001,11935001);the CAS Center for Excellence in Particle Physics(CCEPP)。
We thoroughly investigate both transverse momentum and threshold resummation effects on scalar-pseudoscalar pair production via quark-antiquark annihilation at the 13 TeV Large Hadron Collider at QCD NLO+NLL accuracy....

Invariant-mass distribution of top-quark pairs and top-quark mass determination
《Chinese Physics C》2020年第9期1-6,共6页Wan-Li Ju Guoxing Wang Xing Wang Xiaofeng Xu Yongqi Xu Li Lin Yang 
Supported in part by the National Natural Science Foundation of China(11975030,11635001,11575004);W.-L.Ju was Supported in part by the China Postdoctoral Science Foundation(2017M610685)。
In this study,we investigate the invariant-mass distribution of top-quark pairs near the 2mt threshold,which strongly influences the determination of the top-quark mass mt.Higher-order non-relativistic corrections lea...

HTL resummation in the light cone gauge
《Chinese Physics C》2018年第4期87-100,共14页Qi Chen De-fu Hou 
Supported by National Natural Science Foundation of China(11375070,11735007,11521064)
The light cone gauge with light cone variables is often used in p QCD calculations in relativistic heavyion collision physics. The Hard Thermal Loops（HTL） resummation is an indispensable technique for hot QCD calcul...

A Mean-Field Treatment in Studying Nuclear Matter Through a Thermodynamic Consistent Resummation Scheme
《Plasma Science and Technology》2012年第5期379-382,共4页舒崧 李家荣 
supported by National Natural Science Foundation of China (Nos.10905018,10875050)
We used the Cornwall, Jackiw and Tomboulis （CJT） resummation scheme to study nuclear matter. In the CJT formalism the meson propagators are treated as the bare propagators and the the higher order loop corrections o...

A Brief Overview of Hard-Thermal-Loop Perturbation Theory
《Communications in Theoretical Physics》2012年第3期409-421,共13页苏楠 
The poor convergence of quantum field theory at finite temperature has been one of the main obstacles in the practical applications of thermal QCD for decades.Here we briefly review the progress of hard-thermal-loop p...

Improved calculation of effective potential and symmetry-restored transition in Higgs model
《Chinese Science Bulletin》1995年第1期15-19,共5页侯德富 王恩科 李家荣 刘连寿 
Project supported in part by the National Natural Science Foundation of China
Early in the 1970s, some authors suggested that the electroweak gauge symmetry should be restored at high enough temperature and density. Recently the electroweak phase transition has attracted much attention, because...
