Bottom Pair Production and Search for Heavy Resonances

TL;DR

This paper explores bottom quark pair production as a new channel for detecting heavy resonances and heavy colored gauge bosons, highlighting interference effects and implications for models explaining top quark asymmetries.

Contribution

It introduces bottom pair production as an alternative search channel for heavy resonances and analyzes interference effects in specific coloron models.

Findings

Interference between Standard Model and new physics can signal heavy resonances.

Non-universal chiral color models may be tested through bottom pair production.

Potential to confirm or exclude models explaining top quark asymmetry.

Abstract

The search for heavy resonances has for long been a part of the physics programme at colliders. Traditionally, the dijet channel has been examined as part of this search. Here, bottom pair production is examined as a possible search channel. The chiral color model (flavor universal as well as non-universal) and the flavor universal coloron model are chosen as templates of models that predict the existence of heavy colored gauge bosons. It is seen that, apart from the resonance, the interference of the Standard Model and new physics amplitudes could provide a useful signal. Of particular interest, is the case of the non-universal chiral color model, as this channel may allow the model to be confirmed or ruled out as the reason behind the forward-backward asymmetry in top pair production.
