Semi-inclusive DIS: Factorization
There has been considerable experimental and theoretical interest in semi-inclusive hadron production in deep inelastic scattering (SIDIS) processes. For example, by studying the polarized and unpolarized SIDIS, one will be able to identify the sea quark distribution and polarization in nucleon, and the experimental results from the HERMES collaboration have revealed nontrivial sea structure in...
متن کاملPhenomenological Applications of Qcd Factorization to Semi-inclusive B Decays
We have systematically investigated the semi-inclusive B decays B → MX, which are manifestations of the quark decay b → Mq, within a framework inspired by QCD-improved factorization. These decays are theoretically clean and have distinctive experimental signatures. We focus on a class of these that do not require any form factor information and therefore may be especially suitable for extractin...
متن کاملExclusive and Semi-inclusive B Decays in QCD Factorization
Applications of QCD factorization to B → φK, charmless B → V V , B → J/ψK(K∗) and semi-inclusive decays B →MX are discussed.
متن کاملNLO Analysis of Semi-inclusive DIS
We present a combined NLO QCD analysis to data on both inclusive and semi-inclusive polarized asymmetries. We also present the NLO corrections to the direct part of the polarized photoproduction of charged hadrons.
متن کاملTransverse Λ Polarization in Semi-inclusive Dis
Extending a previous description of Λ and Λ̄ polarization in unpolarized p -p interactions, within a pQCD factorization scheme with new polarizing fragmentation functions, we give predictions for the transverse polarization of Λ’s and Λ̄’s in semi-inclusive DIS, both with neutral and charged currents. Comparison with existing data is not yet significant, but more experimental results are expected...
