Heavy Neutral Lepton at Same-Sign Muon Collider

Ryuichiro Kitano, Ian Low, Ryutaro Matsudo +2

We explore the discovery potential of heavy neutral leptons (HNLs), motivated by models addressing the origin of neutrino masses, at the proposed high-energy same-sign muon collide…

On cusps in the $I^\cdot^{'}$ potential

Ryuichiro Kitano, Ryutaro Matsudo, Lukas Treuer

The large $N$ analysis of QCD states that the potential for the $I^\cdot^{'}$ meson develops cusps at $I^\cdot^{'} = I ¨ / N_{f}$ , $3 I ¨ / N_{f}$ , $\dots$ , with $N_{f}$ the number of flavors. Furthermore,…

Higgs boson production at $I^¼^{+} I^¼^{+}$ colliders

Yu Hamada, Ryuichiro Kitano, Ryutaro Matsudo +4

We study Higgs boson production at $I^¼^{+} I^¼^{+}$ colliders at high energy. Since both initial-state particles are positively charged, there is no $W$ boson fusion at the leading orde…
