Open AccessGoldstini as the decaying dark matter
We consider a new scenario for supersymmetric decaying dark matter without R-parity violation in theories with goldstini, which arise if supersymmetry is broken independently by multiple sequestered sectors. The ...

Open AccessThe dark side of θ 13, δ CP , leptogenesis and inflation in type-I seesaw
In the context of the type-I seesaw mechanism, it is known that θ 13 is zero and leptogenesis can not be realized if there exists a residual flavor symmetry resulting in the Tri-Bimaximal ...

Open AccessDark matter and lepton flavour violation in a hybrid neutrino mass model
We describe a hybrid model in which the light neutrino mass matrix receives both tree-level seesaw and loop-induced contributions. An additional U(1) gauge symmetry is used to stabilize the lightest right-hand...

Open AccessG2HDM: Gauged Two Higgs Doublet Model
A novel model embedding the two Higgs doublets in the popular two Higgs doublet models into a doublet of a non-abelian gauge group SU(2) H is presented. The Standard Model SU(2)

Open AccessSizable NSI from the SU(2)L scalar doublet-singlet mixing and the implications in DUNE
We propose a novel and simple mechanism where sizable effects of non-standard interactions (NSI) in neutrino propagation are induced from the mixing between an electrophilic second Higgs doublet and a charged ...
