Top-quark mass measurements at the LHC: alternative methods
Marcel Vos (ATLAS, CMS collaborations)
TL;DR
This paper reviews alternative methods for measuring the top-quark mass at the LHC, highlighting recent results from ATLAS and CMS that achieve about 1% precision using cross-section-based techniques.
Contribution
It presents recent top-quark mass measurements using alternative approaches that offer different systematic uncertainties, aiding in refining the overall top-quark mass determination.
Findings
ATLAS and CMS achieved 1% precision in top-quark mass measurements
Cross-section-based methods provide orthogonal systematic uncertainties
Results contribute to the global top-quark mass average
Abstract
Alternative top quark mass determinations can provide inputs to the world average with orthogonal systematic uncertainties and may help to refine the interpretation of the standard method. Among a number of recent results I focus on the extractions by ATLAS and CMS of the top quark pole mass from the top quark pair and tt + 1 jet production cross-section, which have now reached a precision of 1%.
