Hologrphic QCD beyond the leading order
We consider a holographic QCD model for light mesons beyond the leading order in the context of 5-dim gauged linear sigma model on the interval in the AdS5 space. We include two dimension-6 operators in addition to the canonical bulk kinetic terms, and study chiral dynamics of π, ρ, a1 and some of their KK modes. As novel features of dim-6 operators, we get non-vanishing Br(a1 → πγ), the electr...

متن کاملV decays in the perturbative QCD approach
Two-body non-leptonic charmed decays B(s) → D(s)P , D (s)P , D(s)V and D (s)V are analyzed in perturbative QCD approach, where P and V denote the light pseudoscalar meson and vector meson, respectively. We test the D meson wave function by a χ fit with experimental data of six B → DP channels. We give the branching ratios of all the charmed B decay channels, most of which agree with experiments...
متن کاملSpin Asymmetries in Perturbative Qcd and Beyond
Two ideas are presented in this work. First, we show that a more carefu treatment of the hard scattering amplitude in perturbative QCD is not necessarily in disagreement with the experimental data for the proton-proton spin asymmetry A, . The previous bound of A,,,, < 1/3 is attributed to the spectator approximation. NN NN ^J However, the perturbative framework of QCD cannot be reconciled with ...
متن کاملParton Showers beyond the Leading Order: a Factorization Approach *
We discuss recent work on methods for incorporating nonleading QCD corrections in parton shower algorithms. Parton shower Monte Carlo event generators are the main practical tool to describe multi-particle final states in high energy collisions. These event generators couple a leading-order (LO) hard scattering to a showering, treated basically in the leading logarithm approximation. Many nonle...
