Measurement of the z- and x-dependence of the Mean Transverse Momentum
ثبت نشده
چکیده
The mean transverse momenta of hadrons, < P ⊥ >, produced in e + N deep inelastic scattering was studied as a function of the hadron energy fraction z and the Bjorken variable x. The statistical accuracy of the HERMES data permitted to observe at high z differences in < P ⊥ > between hadrons with positive and negative charges, h + , h − and K 0 s for the first time. These differences can presumably be explained by the flavour dependence of the intrinsic transverse momentum distributions of quarks in the initial nucleon.

Studies of Spin-Orbit Correlations with Longitudinally Polarized Target
We are proposing a comprehensive program to study transverse momentum dependence of valence quark transverse and longitudinal spin distributions through measurements of single-spin and double-spin azimuthal asymmetries in semi-inclusive electroproduction of pions using the upgraded JLab 11 GeV polarized electron beam and the CLAS12 detector with a longitudinally polarized proton and deuteron ta...
متن کاملOptimum driving a Z-pinch for soft X-Ray lasers
A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...
متن کاملTransverse Momentum Dependence of Cumulative Pions
In the framework of the recently proposed QCD based parton model for the cumulative phenomena in the interactions with nuclei the dependence of the cumulative pion production rates on the transverse momentum K⊥ is studied. The mean value of K⊥ is found to grow with x in the cumulative region. The obtained results are in agreement with the available experimental data. ∗This work is supported by ...
متن کاملAzimuthal asymmetries of charged hadrons produced muons off longitudinally polarised deuterons at COMPASS
Azimuthal asymmetries in semi-inclusive production of positive (h) and negative hadrons (h) have been measured by scattering of 160 GeV muons off longitudinally polarised deuterons at CERN. The asymmetries were decomposed in several terms, according to their expected modulation as a function of the outgoing hadron azimuthal angle φ. Each term receives contributions from one or several spin and ...
متن کاملTwist-4 effects and Q dependence of diffractive DIS
In this letter we report the direct perturbative QCD evaluation of twist-4 effects in diffractive DIS. They are large and have a strong impact on the Q dependence of diffractive structure functions at large β. Based on the AGK rules, we comment on the possible contribution from diffractive higher twists to ∝ 1 Q corrections to proton structure function at small x. These corrections to the longi...
