Predicting Alignment in a Two Higgs Doublet Model
Karim Benakli, Yifan Chen, Gaëtan Lafforgue-Marmet
We show that a non-abelian global acting on the quartic part of the two Higgs Doublet Model leads, at tree-level, to an automatic alignment without decoupling. An example…
Stochastic gravitational waves from spin-3/2 fields -- Hunting SUSY in the sky
Karim Benakli, Yifan Chen, Peng Cheng +1
Stochastic gravitational waves can be produced during the preheating when out-of-equilibrium particles are produced with an anisotropic stress-tensor. We discuss the case where the…
R-symmetry for Higgs alignment without decoupling
Karim Benakli, Yifan Chen, Gaëtan Lafforgue-Marmet
It has been observed that an automatic alignment without decoupling is predicted at tree-level in a Two-Higgs Doublet Model (2HDM) with extended supersymmetry in the gauge and Higg…
Inflation from the internal volume in type IIB/F-theory compactification
Ignatios Antoniadis, Yifan Chen, George K. Leontaris
We study cosmological inflation within a recently proposed framework of perturbative moduli stabilisation in type IIB/F theory compactifications on Calabi-Yau threefolds. The stabi…
Stripping a supermultiplet of all but one scalar: a microscopic view
Karim Benakli, Yifan Chen
We explain how a single scalar degree of freedom can be obtained from projecting out all the other components of a chiral superfield using simple operators in the microscopic theor…
Perturbative moduli stabilisation in type IIB/F-theory framework
Ignatios Antoniadis, Yifan Chen, George K. Leontaris
We propose a new mechanism of (geometric) moduli stabilisation in type IIB/F-theory four-dimensional compactifications on Calabi-Yau manifolds, in the presence of 7-branes, that do…
