Sequentially loopgenerated quark and lepton mass hierarchies in an extended Inert Higgs Doublet model
/ Hernández, A. ; Kovalenko, Sergey ; Pasechnik, Roman ; Schmidt, Ivan
Extended scalar and fermion sectors offer new opportunities for generating the observed strong hierarchies in the fermion mass and mixing patterns of the Standard Model (SM). [...]

/ Addazi, Andrea ; Marcianò, Antonino ; Pasechnik, Roman
We propose a novel mechanism for the production of gravitational waves in the early Universe that originates from the relaxation processes induced by the QCD phase transition. [...]

Mirror symmetry of quantum Yang–Mills vacua and cosmological implications
/ Addazi, Andrea ; Marcianò, Antonino ; Pasechnik, Roman ; Prokhorov, George
We find an argument related to the existence of a Z2 symmetry for the renormalization group flow derived from the bare Yang–Mills Lagrangian, and show that the cancellation of the vacuum energy may arise motivated both from the renormalization group flow solutions and the effective Yang–Mills action.

Scale hierarchies, symmetry breaking, and particle spectra in SU(3)family extended SUSY trinification
/ CamargoMolina, José E. ; Morais, António P. ; Ordell, Astrid ; Pasechnik, Roman ; et al
A unification of leftright $\mathrm{SU}(3{)}_{L}\times \mathrm{SU}(3{)}_{R}$, color $\mathrm{SU}(3{)}_{C}$, and family $\mathrm{SU}(3{)}_{F}$ symmetries in a maximal rank8 subgroup of ${E}_{8}$ is proposed as a landmark for future explorations beyond the Standard Model (SM). [...]

Heavy charged scalars from c s ¯ $$ c\overline{s} $$ fusion: a generic search strategy applied to a 3HDM with U(1) × U(1) family symmetry
/ CamargoMolina, José ; Mandal, Tanumoy ; Pasechnik, Roman ; Wessén, Jonas
We describe a class of three Higgs doublet models (3HDMs) with a softly broken U(1) × U(1) family symmetry that enforces a Cabibbolike quark mixing while forbidding treelevel flavour changing neutral currents. [...]
