Long-lived Higgsino pairs decaying within the LHC detectors
Francesca Borzumati, Kaoru Hagiwara, Kentarou Mawatari +2
Pair-produced long-lived lightest Higgsinos decaying within a few meters in the LHC detectors are considered. The relatively light nearly-pure Higgsino states object of this study…
Helicity amplitudes in light-cone and Feynman-diagram gauges
Junmou Chen, Kaoru Hagiwara, Junichi Kanzaki +2
Recently proposed Feynman-diagram (FD) gauge propagator for massless and massive gauge bosons is obtained from a light-cone (LC) gauge propagator, by choosing the gauge vector alon…
Helicity amplitudes without gauge cancellation for electroweak processes
Junmou Chen, Kaoru Hagiwara, Junichi Kanzaki +1
In the 5-component representation of weak bosons, the first four components make a Lorentz four vector, representing the transverse and longitudinal polarizations excluding the sca…
Signatures of toponium formation in LHC run 2 data
Benjamin Fuks, Kaoru Hagiwara, Kai Ma +1
We study reported deviations between observations and theoretical predictions associated with the production of a pair of di-leptonically decaying top quarks at the LHC, and we exa…
QED and QCD helicity amplitudes in parton-shower gauge
Kaoru Hagiwara, Junichi Kanzaki, Kentarou Mawatari
We introduce photon and gluon propagators in which the scalar polarization component is subtracted systematically by making use of the BRST invariance of the off-shell vector boson…
Probing the top Yukawa coupling at the LHC via associated production of single top and Higgs
Vernon Barger, Kaoru Hagiwara, Ya-Juan Zheng
We study Higgs boson production associated with single top or anti-top via -channel weak boson exchange at the LHC. The process is an ideal probe of the top quark Yukawa couplin…
