The Higgs mass and natural supersymmetric spectrum from the landscape

open access: yesPhysics Letters B, 2016
In supersymmetric models where the superpotential μ term is generated with μ≪msoft (e.g. from radiative Peccei–Quinn symmetry breaking or compactified string models with sequestration and stabilized moduli), and where the string landscape 1.

Harmonic potential and hadron spectroscopy [PDF]

open access: yesarXiv, 2009
The quark-gluon sea in the hadrons is considered as periodically correlated. Energy levels of Shrodinger equation with harmonic potential is used for describing of the spectrum of hadron masses. In the considered cases the effective potential operating on each particle of ensemble, under certain conditions becomes square-law on displacement from a ...

Uncertainty in the reactor neutrino spectrum and mass hierarchy determination

open access: yesJournal of High Energy Physics, 2019
One of the challenges that must be overcome in order to determine the neutrino mass hierarchy using reactor neutrinos is the theoretical uncertainty in the unoscillated reactor neutrino spectrum: this is one of the reasons why, recently, it was proposed ...

Mass spectrum & linear perturbations of ghost-free multi-spin-2 theory

open access: yesJournal of High Energy Physics
Motivated by the spin-2 nature of gravity, we consider a theory of N $$ \mathcal{N} $$ interacting spin-2 fields, formulated in terms of vielbeins, which has been argued to be free of Boulware-Deser ghost instabilities. This is the only known such theory
