Extra-natural production of superheavy Kaluza-Klein particles
Yusuke Yamada
Gauge fields in extra compact dimensions can drive inflation in the four-dimensional (4D) non-compact spacetime, a scenario known as extra-natural inflation. A time-dependent gauge…

One-loop vacuum energy in 10D super-Yang-Mills theory on magnetized tori with/without 4D N=1 supersymmetric completion
Hiroyuki Abe, Akinari Koichi, Yusuke Yamada
We compute the one-loop vacuum energy in 10 dimensional (10D) super Yang-Mills theory compactified on in the presence of the Abelian magne…

More on scattering processes of dressed particles with a time-dependent mass
Yusuke Yamada
We discuss the scattering process of a scalar field having a time-dependent mass with another scalar field having a constant mass as a toy model of the scattering problems during p…
