The perturbative QCD factorization approach in high energy nuclear collisions
I discuss the systematic modifications to the perturbative QCD factorization approach in high energy l+A, p+A and A+A reactions. These include transverse momentum diffusion manifest in the Cronin effect and a small increase in the dijet acoplanarity; nuclear size enhanced power corrections that lead to shadowing in deeply inelastic scattering and suppression of single and double inclusive hadro...
متن کاملTwo-parton twist-3 factorization in perturbative QCD
Abstract We prove collinear factorization theorem for the process πγ∗ → π at the twist-3 level in the covariant gauge by means of the Ward identity, concentrating on the two-parton case. It is shown that soft divergences cancel and collinear divergences are grouped into the pseudo-scalar and pseudotensor two-parton twist-3 pion distribution amplitudes. The delicate summation of a complete set o...
متن کاملB?J/?(?,K) Decays within QCD Factorization Approach
We used QCD factorization for the hadronic matrix elements to show that the existing data, in particular the branching ratios BR ( ?J/?K) and BR ( ?J/??), can be accounted for this approach. We analyzed the decay within the framework of QCD factorization. We have complete calculation of the relevant hard-scattering kernels for twist-2 and twist-3. We calculated this decays in a special scale ...
متن کاملa synchronic and diachronic approach to the change route of address terms in the two recent centuries of persian language
terms of address as an important linguistics items provide valuable information about the interlocutors, their relationship and their circumstances. this study was done to investigate the change route of persian address terms in the two recent centuries including three historical periods of qajar, pahlavi and after the islamic revolution. data were extracted from a corpus consisting 24 novels w...
15 صفحه اولV 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...
