B to light meson transition form factors calculated in perturbative QCD approach
Cai-Dian Lu, Mao-Zhi Yang
We calculate the , (P: light pseudoscalar meson, V light vector meson) form factors in the large-recoil limit in perturbative QCD approach, including both the vect…
Wolfenstein-like Parametrization of the Neutrino Mixing Matrix
Zhi-zhong Xing
We show that the lepton flavor mixing matrix can be expanded in powers of a Wolfenstein-like parameter , which measures the streng…
Introducing Small-World Network Effect to Critical Dynamics
Jian-Yang Zhu, Han Zhu
We analytically investigate the kinetic Gaussian model and the one-dimensional kinetic Ising model on two typical small-world networks (SWN), the adding-type and the rewiring-type.…
Anomalous Gauge Interactions of the Higgs Boson: Precision Constraints and Weak Boson Scatterings
Hong-Jian He, Yu-Ping Kuang, C. -P. Yuan +1
Interaction of Higgs scalar (H) with weak gauge bosons (V=W,Z) is the {\it key} to understand electroweak symmetry breaking (EWSB) mechanism. New physics effects in the HVV interac…
Non-minimally Coupled Tachyon and Inflation
Yun-Song Piao, Qing-Guo Huang, Xinmin Zhang +1
In this paper, we consider a model of tachyon with a non-minimal coupling to gravity and study its cosmological effects. Regarding inflation we will show that for a specific coupli…
Four-Zero Texture of Hermitian Quark Mass Matrices and Current Experimental Tests
Harald Fritzsch, Zhi-zhong Xing
We show that the four-zero texture of Hermitian quark mass matrices can survive current experimental tests: it is able to yield sufficiently large predictions for the flavor mixing…
