Renormalization group equations and matching in a general quantum field theory with kinetic mixing
Renato M. Fonseca, Michal Malinsky, Florian Staub
We work out a set of simple rules for adopting the two-loop renormalization group equations of a generic gauge field theory given in the seminal works of Machacek and Vaughn to the…
Light color octet scalars in the minimal SO(10) grand unification
Stefano Bertolini, Luca Di Luzio, Michal Malinsky
We analyze the relation between the present (and foreseen) bounds on matter stability and the presence of TeV-scale color octet scalar states in nonsupersymmetric SO(10) grand unif…
Fun with the Abelian Higgs Model
Michal Malinsky
In calculations of the elementary scalar spectra of spontaneously broken gauge theories there is a number of subtleties which, though often unnecessary to deal with in the order-of…
Structure and prospects of the simplest SO(10) GUTs
Stefano Bertolini, Luca Di Luzio, Michal Malinsky
We recapitulate the latest results on the class of the simplest SO(10) grand unified models in which the GUT-scale symmetry breaking is triggered by an adjoint Higgs representation…
Towards a New Minimal SO(10) Unification
Stefano Bertolini, Luca Di Luzio, Michal Malinsky
We argue that non-supersymmetric SO(10) models based on a renormalizable Higgs sector in which spontaneous symmetry breaking is triggered by the VEVs of a 45-dimensional adjoint an…
Seesaw Scale in the Minimal Renormalizable SO(10) Grand Unification
Stefano Bertolini, Luca Di Luzio, Michal Malinsky
Simple SO(10) Higgs models with the adjoint representation triggering the grand-unified symmetry breaking, discarded a long ago due to inherent tree-level tachyonic instabilities i…
Hefty MSSM-like light Higgs in extended gauge models
Martin Hirsch, Michal Malinsky, Werner Porod +2
It is well known that in the MSSM the lightest neutral Higgs h^0 must be, at the tree level, lighter than the Z boson and that the loop corrections shift this stringent upper bound…
Running soft parameters in SUSY models with multiple U(1) gauge factors
Renato M. Fonseca, Michal Malinsky, Werner Porod +1
We generalize the two-loop renormalization group equations for the parameters of the softly broken SUSY gauge theories given in the literature to the most general case when the gau…
Non-standard antineutrino interactions at Daya Bay
Rupert Leitner, Michal Malinsky, Bedrich Roskovec +1
We study the prospects of pinning down the effects of non-standard antineutrino interactions in the source and in the detector at the Daya Bay neutrino facility. It is well known t…
Minimal Flipped SO(10) x U(1) Supersymmetric Higgs Model
Stefano Bertolini, Luca Di Luzio, Michal Malinsky
We investigate the conditions on the Higgs sector that allow supersymmetric SO(10) grand unified theories (GUT) to break spontaneously to the standard electroweak model (SM) at the…
The quantum vacuum of the minimal SO(10) GUT
Stefano Bertolini, Luca Di Luzio, Michal Malinsky
We reexamine the longstanding no-go excluding all potentially viable SO(10) -> SU(3)_c x SU(2)_L x U(1)_Y symmetry breaking patterns within the minimal renormalizable non-supersymm…
Flavour structure of supersymmetric SO(10) GUTs with extended matter sector
Martin Heinze, Michal Malinsky
We discuss in detail the flavour structure of the supersymmetric SO(10) grand unified models with the three traditional 16-dimensional matter spinors mixed with a set of extra 10-d…
Renormalization group running of neutrino parameters in the inverse seesaw model
Johannes Bergstrom, Michal Malinsky, Tommy Ohlsson +1
We perform a detailed study of the renormalization group equations in the inverse seesaw model. Especially, we derive compact analytical formulas for the running of the neutrino pa…
The Hunt for New Physics at the Large Hadron Collider
P. Nath, B. D. Nelson, H. Davoudiasl +84
The Large Hadron Collider presents an unprecedented opportunity to probe the realm of new physics in the TeV region and shed light on some of the core unresolved issues of particle…
On the vacuum of the minimal nonsupersymmetric SO(10) unification
Stefano Bertolini, Luca Di Luzio, Michal Malinsky
We study a class of nonsupersymmetric SO(10) grand unified scenarios where the first stage of the symmetry breaking is driven by the vacuum expectation values of the 45-dimensional…
Quark mixing sum rules and the right unitarity triangle
Stefan Antusch, Stephen F. King, Michal Malinsky +1
In analogy with the recently proposed lepton mixing sum rules, we derive quark mixing sum rules for the case of hierarchical quark mass matrices with 1-3 texture zeros, in which th…
Intermediate scales in non-supersymmetric SO(10) grand unified theories
Michal Malinsky
It is often argued that in the class of non-supersymmetric SO(10) grand unified theories there is barely any room for reconciling the lower bound on the position of the GUT scale e…
Non-unitarity effects in the minimal inverse seesaw model
Michal Malinsky
A minimal version of the inverse seesaw model featuring only two pairs of TeV-scale singlet neutrinos is discussed from the perspective of non-standard neutrino interactions. A par…
Non-unitary neutrino mixing and CP violation in the minimal inverse seesaw model
Michal Malinsky, Tommy Ohlsson, Zhi-zhong Xing +1
We propose a simplified version of the inverse seesaw model, in which only two pairs of the gauge-singlet neutrinos are introduced, to interpret the observed neutrino mass hierarch…
Non-unitarity effects in a realistic low-scale seesaw model
Michal Malinsky, Tommy Ohlsson, He Zhang
We analyze the structure of the non-unitary leptonic mixing matrix in the inverse seesaw model with heavy singlets accessible at the LHC. In this model, unlike in the usual TeV see…
Intermediate mass scales in the non-supersymmetric SO(10) grand unification: a reappraisal
Stefano Bertolini, Luca Di Luzio, Michal Malinsky
The constraints of gauge unification on intermediate mass scales in non-supersymmetric SO(10) scenarios are systematically discussed. With respect to the existing reference studies…
Non-Standard Neutrino Interactions from a Triplet Seesaw Model
Michal Malinsky, Tommy Ohlsson, He Zhang
We investigate non-standard neutrino interactions (NSIs) in the triplet seesaw model featuring non-trivial correlations between NSI parameters and neutrino masses and mixing parame…
Perturbative Estimates of Lepton Mixing Angles in Unified Models
Stefan Antusch, Stephen F. King, Michal Malinsky
Many unified models predict two large neutrino mixing angles, with the charged lepton mixing angles being small and quark-like, and the neutrino masses being hierarchical. Assuming…
Solving the SUSY Flavour and CP Problems with Non-Abelian Family Symmetry and Supergravity
Stefan Antusch, Stephen F. King, Michal Malinsky +1
Can a theory of flavour capable of describing the spectrum of fermion (including neutrino) masses and mixings also contain within it the seeds for a solution of the SUSY flavour an…
