Description
It is an important task in the SM to constrain the CP property of the Higgs boson, which still exhibits a large uncertainty. We propose a novel observable at the LHC to probe the CP structure of Higgs coupling to the top quark by employing the linear polarization of gluon jets. The linear polarization induces a preferred direction for the azimuthal energy distribution in the gluon jet, which corresponds directly to the CP phase of the Higgs-top coupling. By constructing an infrared safe transverse spherocity observable for the gluon jet, we show that this new approach has a significant power in constraining the CP property of Higgs boson, complementary to the methods that are currently used in the experimental analysis.
