“…It is important to stress that s c is not necessarily the same for σ pp tot (s) and σ pp tot (s). In this energy regime, it is assumed the odderon is the leading particle exchange [51,52]. As well-known, the odderon has C = −1 parity, which explains the different patterns observed in the σ pp tot (s) and σ pp tot (s) experimental data in this energy range [51].…”

In this paper, one discusses the effects of the Tsallis entropy on the radial pressure distribution in the proton. Using a damped confinement potential the pressure distribution is obtained from the Tsallis entropy approach, being the entropic-index ω connected with the proton temperature concerning some transition temperature. Then, the approach allows the study of the proton thermal evolution up to the Quark-Gluon Plasma regime. The von Laue stability condition, arising from the pressure distribution results in positive and negative energy regions. An analogy between the results for the radial pressure distribution and the proton-proton and the antiproton-proton total cross section is performed. The negative energy region is identified with the odderon exchange while the positive represents the pomeron exchange dominance above some transition energy √ sc. The hollowness effect is also discussed in terms of the results obtained and the proposed analogy.

“…This result implies that for  ¥ s the pp and pp elastic scattering tends to present the same physical behavior in the forward direction. This behavior is expected to occur due to the leading pomeron exchange [27,28].…”

This paper presents a qualitative explanation for the hollowness effect based on the inelastic overlap function, claiming this result is a consequence of fundamental thermodynamic processes. Using the Tsallis entropy, one identifies the entropic index w with the ratio of the collision energy to critical one in the total cross-section. The integrated probability density function is replaced by the inelastic overlap function, which represents the probability of occurrence of an inelastic event depending on both the collision energy and impact parameter. The Coulomb potential, as well as the confinement potential, are used as naive approaches to describe the (internal) energy of the colliding hadrons. The Coulomb potential in the impact parameter picture is not able to furnish any reliable physical result near the forward direction. However, the confinement potential in the impact parameter space results in the hollowness effect shown by the inelastic overlap function near the forward direction.
