Precision physics with the Proton Spectrometer and diffractive physics measurements from CMS

TL;DR

This paper presents recent CMS and TOTEM results on diffractive physics, including jets and jet gap events, and explores the LHC's potential to detect new physics like anomalous couplings and axion-like particles with high sensitivity.

Contribution

It provides the first sensitivities and limits on quartic anomalous couplings and axion-like particles using the LHC as a gamma-gamma collider, with improved sensitivity over standard methods.

Findings

Results on hard diffraction and diffractive jets from CMS and TOTEM.

First sensitivities on quartic anomalous couplings at high mass.

Enhanced detection sensitivity with 300 fb$^{-1}$ compared to standard methods.

Abstract

We describe recent results from CMS and TOTEM on hard diffraction, diffractive jets and jet gap jet events. We also give the first sensitivities and limits on quartic anomalous couplings and axion-like particles at high mass using the LHC as a $\gamma \gamma$ collider. The predicted sensitivities with 300 fb$^{-1}$ are better by two or three orders of magnitude compared to the more standard methods at the LHC without measuring intact protons after collision
