Abstract

A new determination of the u valence quark distribution function in the proton is obtained from the analysis of identified charged pions, kaons, protons and antiprotons produced in muon-proton and muon-deuteron scattering. The comparison with results obtained in inclusive deep inelastic lepton-nucleon scattering provides a further test of the quark-parton model. The u quark fragmentation functions into positive and negative pions, kaons, protons and antiprotons are also measured.

Multiplicities of charged kaons from deep-inelastic muon scattering off an isoscalar target
2017, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
Precise measurements of charged-kaon multiplicities in deep inelastic scattering were performed. The results are presented in three-dimensional bins of the Bjorken scaling variable x, the relative virtual-photon energy y, and the fraction z of the virtual-photon energy carried by the produced hadron. The data were obtained by the COMPASS Collaboration by scattering $160 GeV$ muons off an isoscalar ⁶LiD target. They cover the kinematic domain $1 {(GeV / c)}^{2} < Q^{2} < 60 {(GeV / c)}^{2}$ in the photon virtuality, $0.004 < x < 0.4$ , $0.1 < y < 0.7$ , $0.20 < z < 0.85$ , and $W > 5 GeV / c^{2}$ in the invariant mass of the hadronic system. The results from the sum of the z-integrated $K^{+}$ and $K^{-}$ multiplicities at high x point to a value of the non-strange quark fragmentation function larger than obtained by the earlier DSS fit.
Parton fragmentation functions
2016, Progress in Particle and Nuclear Physics
The field of fragmentation functions of light quarks and gluons is reviewed. In addition to integrated fragmentation functions, attention is paid to the dependence of fragmentation functions on transverse momenta and on polarization degrees of freedom. Higher-twist and di-hadron fragmentation functions are considered as well. Moreover, the review covers both theoretical and experimental developments in hadron production in electron–positron annihilation, deep-inelastic lepton–nucleon scattering, and proton–proton collisions.
Strange and non-strange sea quark-gluon effects in nucleons
2014, Nuclear Physics A
Within a statistical approach, strange and non-strange quark–gluon Fock state contributions are analyzed for their low energy properties. A suitable wave function is written for a nucleon that consists of three valence quarks (qqq) and the sea ( $g, q \bar{q}$ ). Expansion of the nucleonic system in terms of Fock states that contain ( $g, q \bar{q}$ ) is assumed and the probabilities of all possible Fock states, that lead to such a wave-function containing strange and non-strange quark–gluon contents in the sea are determined. Various approximations are entertained to validate the authenticity of the model used. The statistically determined coefficients strongly favor a vector-dominated sea where the sea includes $s \bar{s}$ pairs. Additionally, the sea is constrained to have a limited number of components. The phenomenological implications that affect the low energy properties are discussed. The obtained results are compared to existing theoretical models and experimental data.
Importance of sea contribution to nucleons
2012, Nuclear Physics A
We studied the statistical model of nucleons consisting of sea having various quark–gluon Fock states in addition to valence quarks. Using statistical consideration and taking 86% of the total Fock states contributing to the low energy properties of nucleon, we aim to find the contributions to these properties coming from the scalar, vector and tensor sea. We checked its validity against the assumption where the contributions from scalar and tensor sea have been suppressed and justified to be unimportant. We took the approximation that sea is getting a zero contribution from $H_{0} G_{\bar{10}}$ and $H_{1} G_{\bar{10}}$ in three gluon states. Under the above considerations, the calculated magnetic moment, spin distribution and weak decay coupling constant ratio for proton and neutron states have been tabulated. We hereby confirm that the suppression of the scalar and tensor sea leads to modification in the parameters of the nucleons showing deviation from the experimental data.
Quark helicity distributions from longitudinal spin asymmetries in muon-proton and muon-deuteron scattering
2010, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
Double-spin asymmetries for production of charged pions and kaons in semi-inclusive deep-inelastic muon scattering have been measured by the COMPASS experiment at CERN. The data, obtained by scattering a 160 GeV muon beam off a longitudinally polarised NH₃ target, cover a range of the Bjorken variable x between 0.004 and 0.7. A leading order evaluation of the helicity distributions for the three lightest quarks and antiquark flavours derived from these asymmetries and from our previous deuteron data is presented. The resulting values of the sea quark distributions are small and do not show any sizable dependence on x in the range of the measurements. No significant difference is observed between the strange and antistrange helicity distributions, both compatible with zero. The integrated value of the flavour asymmetry of the helicity distribution of the light-quark sea, $Δ \bar{u} - Δ \bar{d}$ , is found to be slightly positive, about 1.5 standard deviations away from zero.

The inclusive $A_{1, p}$ and hadron double-spin asymmetries $A_{p}^{π +}$ , $A_{p}^{π -}$ , $A_{p}^{K +}$ , $A_{p}^{K -}$ measured at COMPASS (CERN SPS) in deep-inelastic scattering of a polarized muon beam off a polarized NH₃ solid target are presented. The results have been obtained with the full statistics collected in 2007 for the longitudinal target polarization. Proton asymmetries have been combined with published deuteron ones. An evaluation of the non-singlet spin-dependent structure function $g_{1}^{N S} (x, Q^{2})$ and its first moment, which confirms the validity of the Bjorken sum-rule, is presented. A LO evaluation of polarized quark densities is also presented. The use of the proton data allows to perform a full flavor separation and to extract individual helicity densities of u, d, $\bar{u}$ , $\bar{d}$ and s quarks. All sea quark densities are found to be compatible with zero in the full range of the measurements.
