روش خودسازگار در محاسبه نسبت با استفاده از تابع ساختار و نسبت EMC هسته‌های He3 و H3

By using the convolution formalism which consists of Fermi motion and binding effect, we investigate the deep inelastic electron scattering from A=3 mirror in the deep-valence region. The initial valence quark input is taken from the GRVs (Gluck, Reya and Vogt) fitting procedure and the next-to-leading order QCD evolution on FP2 (x,Q2) which gives very good fit to the available data in the (x,Q...

Dynamic Time Scales in Colored Glass Nuclear Matter

Ultra high energy collisions between heavy nuclei can be employed to experimentally probe the QCD properties of dense quark-gluon systems [1, 2, 3, 4, 5]. The properties of the high density quark gluon system have also been compared to a color glass[6, 7, 8, 9, 10, 11, 12, 13]. High energy proton-proton scattering also probes the QCD vacuum. The QCD vacuum differs from the QED vacuum via proper...

Measurements of High Density Matter at Rhic

QCD predicts a phase transition between hadronic matter and a Quark Gluon Plasma at high energy density. The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory is a new facility dedicated to the experimental study of matter under extreme conditions. I will discuss the first round of experimental results from colliding heavy nuclei at RHIC and our current understanding of t...

QCD at small x and nucleus-nucleus collisions

At large collision energy √ s and relatively low momentum transfer Q, one expects a new regime of Quantum Chromo-Dynamics (QCD) known as “saturation”. This kinematical range is characterized by a very large occupation number for gluons inside hadrons and nuclei; this is the region where higher twist contributions are as large as the leading twist contributions incorporated in collinear factoriz...
