Possible mixing between elementary and bound state fields in the production excess at the LHC
Yoshiki Matsuoka
Recent report by CMS Collaboration on the excess of top and anti-top pair production is studied, under the hypothesis of the coexistence of a toponium and an additional ele…
Tripling Fluctuations and Peaked Sound Speed in Fermionic Matter
Hiroyuki Tajima, Kei Iida, Toru Kojo +1
A crossover involving three-fermion clusters is relevant to the hadron-quark crossover, which, if occurring in a neutron star, could naturally reproduce the dense-matter equation o…
On the Effects of Elementary and Bound State Fields on Vacuum Stability in Production at the LHC
Yoshiki Matsuoka
The recent report by the CMS Collaboration on the excess of top and anti-top pair production is examined with regard to the improvement of vacuum stability under two simple scenari…
Prediction of the Dark Fermion Mass using Multicritical-Point Principle
Yoshiki Matsuoka
This paper proposes a method to determine the effective potential using the multicritical-point principle (MPP) under the additional scalar field. The MPP is applied to the model i…
Higgs Inflation, Vacuum Stability, and Leptogenesis
Neil D. Barrie, Akio Sugamoto, Tatsu Takeuchi +1
We consider the introduction of a complex scalar field carrying a global lepton number charge to the Standard Model and the Higgs inflation framework. The conditions are investigat…
Pendulum Leptogenesis
Kazuharu Bamba, Neil D. Barrie, Akio Sugamoto +2
We propose a new non-thermal Leptogenesis mechanism that takes place during the reheating epoch, and utilizes the Ratchet mechanism. The interplay between the oscillation of the in…
Vacuum Magnetic Birefringence Experiment as a probe of Dark Sector
Xing Fan, Shusei Kamioka, Kimiko Yamashita +2
Vacuum magnetic birefringence (VMB) is a nonlinear electromagnetic effect predicted by QED. In addition to the effect from QED, the effect also has a possibility to probe the dark…
Generalized Heisenberg-Euler formula in Abelian gauge theory with parity violation
Kimiko Yamashita, Xing Fan, Shusei Kamioka +2
A generalized Heisenberg-Euler formula is given for an Abelian gauge theory having vector as well as axial vector couplings to a massive fermion. So, the formula is applicable to a…
Ratchet Baryogenesis with an Analogy to the Forced Pendulum
Kazuharu Bamba, Neil D. Barrie, Akio Sugamoto +2
A new scenario of baryogenesis via the ratchet mechanism is proposed based on an analogy to the forced pendulum. The oscillation of the inflaton field during the reheating epoch af…
