Low-energy Bremsstrahlung photon in relativistic nucleon+nucleon collisions

TL;DR

This paper investigates low-energy Bremsstrahlung photon production in relativistic nucleon collisions, revealing dependence on electromagnetic current reduction and collision type, with implications for understanding collision dynamics.

Contribution

It introduces the concept of deceleration time in modeling Bremsstrahlung photon spectra and compares photon emissions in p+p and p+n collisions.

Findings

Photon spectrum at low energy is independent of deceleration time.

Spectrum becomes softer with increasing deceleration time.

Differences observed between p+p and p+n collision spectra.

Abstract

We study the production of Bremsstrahlung photon in relativistic nucleon+nucleon collisions by introducing a deceleration time of electromagnetic currents. It is found that Bremsstrahlung photon spectrum at low energy does not depend on the deceleration time but solely on the amount of reduced electromagnetic current in collision. On the other hand, the photon spectrum becomes soft with increasing deceleration time. We also find that Bremsstrahlung photon spectrum in p+n collisions is considerably different from that in p+p collisions at low energy.
