abstract

In this work, we study the electric and magnetic Sachs form factors for proton and neutron by using a deformed gravity/gauge model. We describe holographically baryons as well as gauge bosons which are ruled by the parameters $k_{B}$ and $k_\gamma$, associated with confinement and kinematical energy scales, respectively. Then, we construct the interaction action and calculate the electric and magnetic form factors for the proton and the neutron, and their electromagnetic sizes. The obtained results are compatible with those found in the literature from experimental and theoretical data.

  1. Implications of exclusive photon leptoproduction measurements for the proton charge-radius puzzle

    hep-ph 2026-07 conditional novelty 5.0 of 10

    After excluding or cutting low-|t| CLAS 2018 data, BH-dominated EP measurements yield a proton charge radius smaller than the PDG average and consistent with PRad and muonic hydrogen.

  2. Nucleon spectra and wave functions from holographic models with dual Einstein-dilaton and Starobinsky-dilaton gravities

    hep-th 2026-07 conditional novelty 4.0 of 10

    Adding a fitted λ parameter and Starobinsky αR² corrections lets holographic Einstein-dilaton models reproduce the nucleon radial-excitation spectrum with errors as low as 0.29%.

  3. Mechanical properties of the proton from a deformed AdS holographic model

    hep-ph 2025-11 conditional novelty 4.0 of 10

    A deformed AdS holographic model with a Dirac proton computes the gluon gravitational form factor A in good agreement with lattice QCD after normalizing the zero point, but the D-term and derived pressure/shear distri...

  4. Dynamics of chiral phase transition in a $N_f=2+1$ soft-wall AdS/QCD model

    hep-ph 2025-07 conditional novelty 4.0 of 10

    In a 2+1 flavor soft-wall AdS/QCD model, the chiral condensate exhibits slow, non-trivial relaxation with a metastable plateau or overshoot when quenched close to the phase transition.
