Arranging Dirac covariants in hadronic Bethe-Salpeter wave functions for pseudoscalar meson decays
Shashank Bhatnagar, Shi-Yuan Li, Jorge Mahecha
We have employed the framework of Bethe-Salpeter equation under covariant instantaneous ansatz to calculate leptonic decay constants of unequal mass pseudoscalar mesons like pi, K,…
Study of Decays in the Family Non-universal Models
Cheng-Wei Chiang, Run-Hui Li, Cai-Dian Lü
In a combined investigation of the decays, constraints on the related couplings in family non-universal models are derived. We find that wit…
LHC Signals for Coset Electroweak Gauge Bosons in Warped/Composite PGB Higgs Models
Kaustubh Agashe, Aleksandr Azatov, Tao Han +3
The framework of a warped extra dimension with the Standard Model (SM) fields propagating in it is a very well-motivated extension of the SM since it can address both the Planck-we…
Multiple Parton Scattering in Nuclei: Modified DGLAP Evolution for Fragmentation Functions
Wei-tian Deng, Xin-Nian Wang
Within the framework of generalized factorization of higher-twist contributions to semi-inclusive cross section of deeply inelastic scattering off a large nucleus, multiple parton…
Decays of meson to two charmed mesons
Run-Hui Li, Xiao-Xia Wang, A. I. Sanda +1
The factorization theorem in Decays of mesons to two charmed mesons (both pseudoscalar and vector) can still be proved in the leading order in and $Λ_{\rm{QCD}}…
Transverse momentum dependent quark distributions and polarized Drell-Yan processes
Jian Zhou, Feng Yuan, Zuo-Tang Liang
We study the spin-dependent quark distributions at large transverse momentum. We derive their transverse momentum behaviors in the collinear factorization approach in this region.…
