Pion fluctuation in deep inelastic scattering
The forward neutron production in the ep collisions at 300 GeV measured by the H1 and ZEUS Collaborations at DESY has been used to estimate the total probability for the proton fluctuation into nπ and pπ. The probability found is on the order of the 30%. This number is compared with the numbers of obtained for the probability of quark fluctuation into π from several alternative DIS processes (G...
متن کاملDeep Inelastic Scattering at HERA
Inclusive production of D(2010) mesons in deep inelastic scattering has been measured using ep and ep data obtained with the ZEUS detector at HERA using integrated luminosities of 16.7 and 65.2pb, respectively. The decay channel D → Dπ with D → Kπ and corresponding antiparticle decays were used to identify D mesons. The D cross sections in ep and ep interactions agree with NLO QCD predictions, ...
متن کاملMeson Structure in Deep Inelastic Scattering
We study the deep inelastic structure functions of mesons within the Nambu and JonaLasinio model. We calculate the valence quark distributions in π, K, and ρ mesons at the low energy model scale, which are evoluted to the experimental momentum scale in terms of the Altarelli-Parisi equation. The resulting distribution functions show reasonable agreements with experiment. We also discuss the sem...
متن کاملPhenomenology of Deep Inelastic Scattering Structure Functions
I review recent progress in analysing deep inelastic scattering structure functions in global analyses. The new ingredients are new data and attempts to incorporate heavy quarks consistently. A new way of including the resummation of large log 1/x terms is discussed. INTRODUCTION Since we last met in Rome last year there has been progress in our understanding of deep inelastic scattering (DIS) ...

ν = q · P M = E − E′ is the lepton’s energy loss in the nucleon rest frame (in earlier literature sometimes ν = q · P ). Here, E and E′ are the initial and final lepton energies in the nucleon rest frame. Q2 = −q2 = 2(EE′−−→k · −→k ′)−m2 −m2 ′ where m (m ′) is the initial (final) lepton mass. If EE′ sin2(θ/2) m2 , m2 ′ , then ≈ 4EE′ sin2(θ/2), where θ is the lepton’s scattering angle with respe...
