Uncertainties on exclusive diffractive Higgs and jets production at the LHC

TL;DR

This paper compares two theoretical models for exclusive diffractive Higgs and jets production at the LHC, assesses their uncertainties, and discusses how early measurements can significantly reduce these uncertainties.

Contribution

It implements and compares two models into the FPMC generator and evaluates how early LHC data can constrain theoretical uncertainties in exclusive production.

Findings

Current uncertainties can be reduced by a factor of 5 with early measurements.

Models show different predictions that can be tested against CDF data.

Early LHC measurements are crucial for constraining exclusive Higgs production predictions.

Abstract

Two theoretical descriptions of exclusive diffractive jets and Higgs production at the LHC were implemented into the FPMC generator: the Khoze, Martin, Ryskin model and the Cudell, Hern\'andez, Ivanov, Dechambre exclusive model. We then study the uncertainties. We compare their predictions to the CDF measurement and discuss the possibility of constraining the exclusive Higgs production at the LHC with early measurements of exclusive jets. We show that the present theoretical uncertainties can be reduced with such data by a factor of 5.
