Hadron Distributions in a Quark - Parton Model
نویسنده
چکیده
We present distributions in longitudinal and transverse momentum for hadrons produced in various deep inelastic processes for a particular picture of quark dressing. The sensitivity of various parameters in the model to presently available data is explored. Predictions are also made for the correlations expected in proton-proton scattering events which yield a high transverse momentum pion or kaon, assuming that these originate from a similar quark dressing process.

Generalized parton correlation functions for a spin-1/2 hadron
Abstract: The fully unintegrated, off-diagonal quark-quark correlator for a spin-1/2 hadron is parameterized in terms of so-called generalized parton correlation functions. Such objects, in particular, can be considered as mother distributions of generalized parton distributions on the one hand and transverse momentum dependent parton distributions on the other. Therefore, our study provides ne...
متن کاملGeneralized parton correlation functions for a spin-0 hadron
The fully unintegrated, off-diagonal quark-quark correlator for a spin-0 hadron is parameterized in terms of so-called generalized parton correlation functions. Such objects are of relevance for the phenomenology of certain hard exclusive reactions. In particular, they can be considered as mother distributions of generalized parton distributions on the one hand and transverse momentum dependent...
متن کاملParton distributions in the proton and pion
We use detailed balance for a hadron composed of quark and gluon Fock states to obtain parton distributions in the proton and pion on the basis of a simple statistical model.
متن کاملUnintegrated parton distributions and electroweak boson production at hadron colliders
We describe the use of doubly-unintegrated parton distributions in hadron-hadron collisions, using the (z, kt)-factorisation prescription where the transverse momentum of the incoming parton is generated in the last evolution step. We apply this formalism to calculate the transverse momentum (PT ) distributions of produced W and Z bosons and compare the predictions to Tevatron Run 1 data. We fi...

An alternative calculation of the lowest order electroweak radiative corrections (EWC) to the single W-boson production in hadron-hadron collision in the framework of the quark parton model without any absorption of the collinear quark singularity into the parton distributions is carried out. Numerical analysis under Tevatron and LHC kinematic conditions is performed.
متن کاملQuark Distribution Function in Pion within Instanton Liquid Model
We calculate the leading-twist valence-quark distribution function in the pion at a low normalization scale of an order of the inverse average size of an instanton ρc. The quark-pion dynamics and the construction of the quark-pion vertex function are considered in the framework of the instanton liquid model. The parameters of instanton vacuum, the effective instanton radius and quark mass, are ...
