Ultraviolet Sensitivity in Higgs-Starobinsky Inflation
Sung Mook Lee, Tanmoy Modak, Kin-ya Oda +1
The general scalar-tensor theory that includes all the dimension-four terms has parameter regions that can produce successful inflation consistent with cosmological observations. T…
Probing first-order electroweak phase transition via primordial black holes in the effective field theory
Katsuya Hashino, Shinya Kanemura, Tomo Takahashi +1
We investigate production of primordial black holes from first-order electroweak phase transition in the framework of the nearly aligned Higgs effective field theory, in which non-…
Sneutrinos as two inflatons and curvaton and leptogenesis
Tomo Takahashi, Toshifumi Yamada, Shuichiro Yokoyama
We argue that sneutrinos can be embedded in a multi-field inflation framework where two inflatons and a curvaton simultaneously contribute to primordial fluctuations, which is cons…
Primordial black holes as a probe of strongly first-order electroweak phase transition
Katsuya Hashino, Shinya Kanemura, Tomo Takahashi
Primordial black holes can be produced by density fluctuations generated from delayed vacuum decays of first-order phase transition. The primordial black holes generated at the ele…
The -Higgs inflation with two Higgs doublets
Sung Mook Lee, Tanmoy Modak, Kin-ya Oda +1
We study -Higgs inflation in a model with two Higgs doublets in which the Higgs sector of the Standard Model is extended by an additional Higgs doublet, thereby four scalar fi…
Smallest Halos in Thermal Wino Dark Matter
Shin'ichiro Ando, Ayuki Kamada, Toyokazu Sekiguchi +1
(Mini) split supersymmetry explains the observed Higgs mass and evades stringent constraints, while keeping good features of TeV-scale supersymmetry other than the little hierarchy…
