G. Pancheri, Y. N. Srivastava, O. Shekhovtsova
TL;DR
This paper proposes a new mechanism for the forward peak in elastic proton-proton scattering, inspired by a resummation technique in QED for soft photon emission, suggesting a zero momentum mode in QCD.
Contribution
It introduces an ansatz linking a zero momentum mode in QCD to the forward peak in pp elastic scattering, inspired by QED resummation methods.
Findings
Proposes a mechanism for the forward peak in pp scattering.
Links QED resummation techniques to QCD phenomena.
Suggests a zero momentum mode plays a role in elastic scattering.
Abstract
We recall a resummation procedure in QED to extract the zero momentum mode in soft photon emission and present an ansatz about a possible mechanism for the forward peak characterizing elastic proton proton scattering.
