CDF experimental results on diffraction

TL;DR

This paper reviews experimental results on diffraction from the Fermilab Tevatron collider, including measurements of the diffractive structure function, t-distribution, and various diffractive processes, providing insights into diffraction at high energies.

Contribution

It presents new experimental measurements of diffraction phenomena at the Tevatron, including the diffractive structure function and t-distribution for both soft and hard events, expanding understanding of diffraction mechanisms.

Findings

Diffractive structure function measured up to Q^2=10,000 GeV^2

t-distribution characterized for soft and hard diffractive events

Observation of diffractive W/Z production and exclusive processes

Abstract

Experimental results on diffraction from the Fermilab Tevatron collider obtained by the CDF experiment are reviewed and compared. We report on the diffractive structure function obtained from dijet production in the range $0<Q^2<10,000$ GeV$^2$, and on the $|t|$ distribution in the region $0<|t<1$ GeV$^2$ for both soft and hard diffractive events up to $Q^2\approx 4,500$ GeV$^2$. Results on single diffractive W/Z production, forward jets, and central exclusive production of both dijets and diphotons are also presented.
