Weak interaction contribution to the inclusive hadron-hadron scattering cross sections at high $p_T$

TL;DR

This paper shows that weak interactions significantly influence the high transverse momentum hadron production in proton-antiproton collisions, explaining observed deviations from expected scaling behavior at Tevatron energies.

Contribution

It is the first to identify and quantify the impact of weak interactions on inclusive hadron-hadron scattering cross sections at high energies.

Findings

Weak interactions cause observable scaling violations in high $p_T$ hadron production.

The weak interaction contribution increases with collision energy.

Weak effects become significant at Tevatron energy scales.

Abstract

It is demonstrated that the strong power-like scaling violation in the transverse momentum distribution of inclusive hadron production, observed by CDF Collaboration in $\bar{p}p$ collisions at Tevatron is caused by contribution of weak interaction. The contribution of weak interaction is increasing with energy at high energies.
