Revisiting Large Neutrino Magnetic Moments
Manfred Lindner, Branimir Radovčić, Johannes Welter
Current experimental sensitivity on neutrino magnetic moments is many orders of magnitude above the Standard Model prediction. A potential measurement of next-generation experiment…
On the Decoupling Theorem for Vacuum Metastability
Hiren H. Patel, Branimir Radovcic
In this paper, we numerically study the impact heavy field degrees of freedom have on vacuum metastability in a toy model, with the aim of better understanding how the decoupling t…
Majorana dark matter in a classically scale invariant model
Sanjin Benic, Branimir Radovcic
We analyze a classically scale invariant extension of the Standard Model with dark gauge broken by doubly charge scalar leaving a remnant symmetry. Dark fermions…
Electroweak breaking and Dark Matter from the common scale
Branimir Radovcic, Sanjin Benic
We propose a classically scale invariant extension of the Standard Model where the electroweak symmetry breaking and the mass of the Dark Matter particle come from the common scale…
Radiative Neutrino Mass with Scotogenic Scalar Triplet
Vedran Brdar, Ivica Picek, Branimir Radovcic
We present radiative one-loop neutrino mass model with hypercharge zero scalar triplet in conjunction with another charged singlet scalar and an additional vectorlike lepton double…
New Scotogenic Model of Neutrino Mass with Gauge Interaction
Ernest Ma, Ivica Picek, Branimir Radovcic
We propose a new realization of the one-loop radiative model of neutrino mass generated by dark matter (scotogenic), where the particles in the loop have an additional gau…
Neutrino Masses and TeV-scale Particles Testable at the LHC
Kresimir Kumericki, Ivica Picek, Branimir Radovcic
We consider a scenario in which TeV-scale particles belonging to weak-isospin multiplets higher than triplets lead to novel seesaw mechanisms different from conventional type I, II…
Enhancement of by seesaw-motivated exotic scalars
Ivica Picek, Branimir Radovcic
We examine the role of seesaw motivated exotic scalars in loop-mediated Higgs decays. We consider a simple TeV-scale seesaw model built upon the fermionic quintuplet mediator in co…
TeV-scale Seesaw with Quintuplet Fermions
Kresimir Kumericki, Ivica Picek, Branimir Radovcic
We propose a new seesaw model based on fermionic hypercharge zero weak quintuplet in conjunction with additional scalar quadruplet which attains an induced vev. The model provides…
Critique of Fermionic R\nuMDM and its Scalar Variants
Kresimir Kumericki, Ivica Picek, Branimir Radovcic
We examine the stability of minimal dark matter (MDM) particle-candidates in the setup in which they participate in radiative neutrino (Rν) masses. We first point out the existence…
Exotic Seesaw-Motivated Heavy Leptons at the LHC
Kresimir Kumericki, Ivica Picek, Branimir Radovcic
We study the LHC potential for discovering TeV-scale SU(2)_L 5-plet fermions introduced recently to explain small neutrino masses. We show that the Drell-Yan production and the dec…
Testing New TeV-scale Seesaw Mediators at the LHC
Ivica Picek, Branimir Radovcic
We propose TeV-scale Dirac fermions producing Majorana masses of the known neutrinos via tree-level seesaw, different from standard type I and III seesaw. The employed weak five-pl…
Role of Higher Fermion Representations in TeV-scale Seesaw
Ivica Picek, Branimir Radovcic
We consider a scenario in which additional vectorlike TeV-scale fermions belonging to higher weak-isospin multiplets provide new seesaw mediators. If these fermions have non-zero h…
Novel TeV-scale seesaw mechanism with Dirac mediators
Ivica Picek, Branimir Radovcic
We propose novel tree level seesaw mechanism with TeV-scale vectorlike Dirac mediators that produce Majorana masses of the known neutrinos. The gauge quantum number assignment to t…
Nondecoupling of a terascale isosinglet quark and rare K and B decays
Ivica Picek, Branimir Radovcic
We examine recent extensions of the standard model with an up-type vectorlike isosinglet T quark that mixes dominantly with the top quark. We take under scrutiny the nondecoupling…
