Determining the gluon condensate with DIS experiments with holographic approach

2021

Using gauge/gravity duality we study deep inelastic scattering (DIS) of a lepton with a proton target in presence of gluon condensation. We adopt a modified AdS5 background in which the modification parameter c corresponds to the gluon condensation in the boundary theory. Firstly in study of electromagnetic field, we find that non-zero c can strengthen magnitude of the field. In the next step, we compute baryonic states wave function equations in which mass of the proton target demands contribution of value of c as c = 0.0120± 0.0005GeV. Proceeding by electromagnetic field and baryonic states, we derive the holographic interaction action that is related to amplitude of the scattering. Eventually we numerically compute the corresponding structure functions as functions of x and q which are Bjorken variable and the momentum lepton transfers respectively. Comparing Jlab Hall C data with our theoretical results, we find that there is a good agreement between theory and phenomenology. E-...

Determining the gluon condensate with DIS experiments at small Bjorken parameter regime

2021

Using gauge/gravity duality we study deep inelastic scattering (DIS) of a lepton with a proton target in presence of gluon condensation. We adopt a modified AdS5 background in which the modification parameter c corresponds to the gluon condensation in the boundary theory. Firstly we study electromagnetic field in such a scattering. Our results show that presence of c strengthen magnitude of electromagnetic field. In the next step, we find baryonic states wave function equations in which mass of the proton target demands contribution of only small values of c. As our main aim is determining value of this parameter, we find c = 0.0120± 0.0005GeV from experimental data. Proceeding by electromagnetic field and baryonic states, we derive the holographic interaction action that is related to amplitude of the scattering. Eventually we compute the corresponding structure functions as functions of Bjorken parameter x and the momentum lepton transfers q numerically. Comparing Jlab Hall C data...
