Shaping the top asymmetry
J. A. Aguilar-Saavedra, M. Perez-Victoria
TL;DR
This paper investigates how light color octets can explain the observed top forward-backward asymmetry profiles across different invariant mass ranges, aligning with collider data.
Contribution
It demonstrates that light color octets can reproduce various top asymmetry profiles while maintaining consistency with Standard Model predictions at Tevatron and LHC.
Findings
Light color octets can match the top asymmetry profiles.
Moderate deviations in t tbar cross sections are achievable.
Compatibility with collider data is maintained.
Abstract
We study different profiles of the distribution of the top forward-backward asymmetry, depending on the invariant mass of the t tbar pair. We show that they can be reproduced by one or more light colour octets, while keeping moderate departures of the t tbar cross section and invariant mass distributions with respect to the Standard Model predictions at Tevatron and LHC.
