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…

Gravitational wave spectrum from expanding string loops on domain walls: Implication for nanohertz pulsar timing array signal

Yu Hamada, Wakutaka Nakano

We analytically calculate the spectrum of stochastic gravitational waves (GWs) emitted by expanding string loops on domain walls in the scenario where domain walls decay by nucleat…
