Calculating Pull for Non-Singlet Jets

Understand

The pull vector is a jet observable sensitive to the distribution of soft radiation controlled by the color flow in a collider event.

• We present calculations to leading order in the soft and collinear limits for the pull vector measured between pairs of jets that do not form a color-singlet dipole.
• Our calculations are presented within the context of $e^+e^-\to$ three jets events, on which pull is measured between the two subleading jets.
• A subset of these calculations can be re-interpreted as a bottom--anti-bottom quark jet pair in a color octet configuration, which can be a background to Higgs production at large boost.
