Finite modular Coleman-Weinberg inflation
Yoshihiko Abe, Komei Goto, Tetsutaro Higaki +2
We propose a modular symmetric inflationary model based on a Coleman--Weinberg potential generated by integrating out heavy vector-like quarks that couple to the complex modulus fi…

Chiral enhancement in the vector-like fourth family: Case of
Junichiro Kawamura, Yuji Omura
We demonstrate that a vector-like fourth family of quarks induces a genuine chiral enhancement in , which is absent in the Standard Model (SM). The coexistence of doublet…

Large and small hierarchies from finite modular symmetries
Tetsutaro Higaki, Junichiro Kawamura, Tatsuo Kobayashi +2
We study the moduli stabilization by the radiative corrections due to the moduli dependent vector-like masses invariant under the finite modular symmetry. The radiative stabilizati…
