Contribution of Orbital Angular Momentum to the Nucleon Spin
Maryam Momeni-Feili, Firooz Arash, Fatemeh Taghavi-Shahri +1
We have calculated the Orbital Angular Momentum of quarks and gluons in the nucleon. The calculations are carried out in the next to leading order utilizing the so-called valon mod…
Polarization Test of Higgs Spin and Parity
Firooz Arash
A polarization test is applied to determine the spin and the parity of the observed resonance at LHC, which is believed to be the expected "Higgs" particle. The test is based on ve…
Transversity Distribution Functions in the Valon Model
Z. Alizadeh Yazdi, F. Taghavi-Shahri, F. Arash +1
By using the valon model, we calculate the Transverse Momentum Distribution functions, TMDs, inside the Nucleon. TMDs indicate the probability to find partons with spin aligned (an…
Non-Singlet spin structure function in the valon model and low x scaling behavior of and
Fatemeh Taghavi Shahri, Firooz Arash
A next-to-leading order QCD calculation of non-singlet spin structure function, is presented within the valon representation of Hadrons. In the valon model, it is ass…
Gluon Polarization In Nucleon
Abolfazl Shahveh, Fatemeh Taghavi-Shahri, Firooz Arash
In the context of the so-called valon model, we calculate and show that although it is small and compatible with the measured values, the gluon contribution to the s…
Valence Quark Polarization In the Nucleon And the Deuteron Data
Firooz Arash, Fatemeh Taghavi-Shahri
Within the framework of the so-called "valon" model, we argue that a substantial part of the nucleon spin, about 40%, is carried by the polarized valence quarks. The remaining is t…
