Azimuthal correlation in lepton-hadron scattering via charged weak-current processes

Azimuthal Correlation in Lepton-Hadron Scattering via Charged Weak-Current Processes

We consider the azimuthal correlation of the final-state particles in charged weak-current processes. This correlation provides a test of perturbative quantum chromodynamics (QCD). The azimuthal asymmetry is large in the semiinclusive processes in which we identify a final-state hadron, say, a charged pion compared to that in the inclusive processes in which we do not identify final-state parti...

Bremsstrahlung in weak charged current polarized lepton - nucleon deep inelastic scattering

The processes of lepton-nucleon scattering, including ones with both polarized beams, at high energy provide relevant information about interaction and particles structure, allowing to analyze nucleon spin structure. As energy and experimental accuracy rise, necessity to improve Born cross sections and polarized asymmetries with higher order radiative corrections becomes substantial. In this re...

Multiplicities in Lepton - Hadron Processes

The average multiplicity at large w (w w s/Q2 + I) is Abstract in deep inelastic electro-and neutrinoproduction related in Feynman's version of the parton model to the average multiplicities in high-energy electron-positron annihilation and hadron-hadron scattering. The relation is: (n(s,Q2)'ep-Ce+e-Jn(Q2/$) + ChBn(o-1) VP where C e+e-and Ch are, respectively, the coefficients of en(s/Myi) in t...

Methods of Testing Lepton Universality using Charged Current Weak Interactions

deep-inelastic lepton-hadron scattering

The most important part of the order α s corrections to the charm component of the charged-current structure functions F2(x,Q ) and F3(x,Q ) have been calculated. This calculation is based on the asymptotic form of the heavy-quark coefficient functions corresponding to the higher order corrections to the W-boson-gluon fusion process. These coefficient functions which are in principle only valid...
