Perturbative description of inclusive single hadron production at HERA
Abstract Light charged hadron production data in the current fragmentation region at HERA are calculated using next-to-leading order perturbative calculations and fragmentation functions obtained from similar data from e+e− reactions. General good agreement is found at large photon virtuality Q2 and intermediate momentum fraction xp, consistent with fragmentation function universality. The desc...
متن کاملToward the non - perturbative description of high energy processes
General implications of existence of non-perturbative scales and hadronic sub-structure for high energy processes are discussed. We propose that the dependence of the cross section of ¯ qq dipoles on their size d should deviate from d 2 when d becomes comparable to substructure scale. Then we discuss Kharzeev-Levin pomeron model [1], based on ladder-type diagrams with scalar resonances (scalar ...
متن کاملPadé - Improved Estimate of Perturbative Contributions to Inclusive Semileptonic
Padé-approximant methods are used to estimate the three-loop perturbative contributions to the inclusive semileptonic b → u decay rate. These improved estimates of the decay rate reduce the theoretical uncertainty in the extraction of the CKM matrix element |V ub | from the measured inclusive semileptonic branching ratio. In this paper we briefly review the development of Padé approximation tec...
متن کاملInclusive B-decay Spectra and Ir Renormalons
B-decay physics is gradually turning into a field of precision phenomenology. Inclusive decay measurements provide some of the most robust tests of the standard model. Classical examples are the rate of B̄ −→ Xsγ decays [1] and constraints on the unitarity triangle through the measurement of Vub from charmless semileptonic decays [2]. The advantage of inclusive measurements over exclusive ones i...
متن کاملPerturbative corrections to zero recoil inclusive B decay sum rules
Comparing the result of inserting a complete set of physical states in a time ordered product of b decay currents with the operator product expansion gives a class of zero recoil sum rules. They sum over physical states with excitation energies less than ∆, where ∆ is much greater than the QCD scale and much less than the heavy charm and bottom quark masses. These sum rules have been used to de...
