Nuclear shadowing in the holographic framework

Area of Science:

• Nuclear Physics
• Quantum Chromodynamics
• High Energy Physics

Background:

• The nucleon structure function F2(N) is crucial for understanding deep inelastic scattering (DIS).
• Holographic frameworks offer a theoretical approach to model nucleon structure.
• Nuclear effects in DIS require specific theoretical treatments.

Purpose of the Study:

• To adapt a holographic framework for calculating nuclear structure functions.
• To investigate the role of rescaling in describing nuclear DIS phenomena.
• To compare theoretical predictions with experimental data in the shadowing region.

Main Methods:

• Computing the nucleon structure function F2(N) within a holographic framework.
• Implementing a rescaling procedure for momentum transfer (Q2) and the infrared hard-wall parameter (z0).
• Calculating nuclear ratios RA = F2(A)/F2(N) using a single rescaling parameter λA for each nucleus.

Main Results:

• The rescaled holographic framework successfully describes nuclear deep inelastic scattering effects.
• Nuclear ratios RA are accurately reproduced by introducing a nucleus-specific rescaling parameter λA.
• The model shows good agreement with experimental data across a wide range of the shadowing region.

Conclusions:

• The holographic approach, with appropriate rescaling, provides a viable method for studying nuclear structure functions.
• Rescaling of Q2 and z0 is essential for bridging theoretical calculations to experimental nuclear DIS data.
• This framework offers a promising tool for exploring nuclear shadowing phenomena.
