Role of the $Z$ polarization in the $H\to b\bar{b}$ measurement

Abstract

It is widely known that the $ZH$ production channel provides a promising probe to the $H\to b\bar{b}$ decay at the LHC, when the Higgs and the $Z$ bosons are highly boosted along the transverse direction. We show how information on the $Z$ boson polarization -- that is disregarded in the current LHC analyses -- can relevantly improve the signal from background discrimination, helping us to observe and achieve a larger precision for the $H\to b\bar{b}$ measurement in the $Z(\ell \ell )H$ channel.
