The Superpartner Spectrum of Gaugino Mediation [PDF]
Phys.Rev.D62:095004,2000, 2000 We compute the superpartner masses in a class of models with gaugino mediation (or no-scale) boundary conditions at a scale between the GUT and Planck scales. These models are compelling because they are simple, solve the supersymmetric flavor and CP problems, satisfy all constraints from colliders and cosmology, and predict the superpartner masses in ...

Lepto-axiogenesis and the scale of supersymmetry [PDF]
Journal of High Energy Physics, 2023 If the Peccei-Quinn field containing the QCD axion undergoes rotations in the early universe, the dimension-five operator responsible for neutrino masses can generate a lepton asymmetry that ultimately gives rise to the observed baryon asymmetry of the ...

Exploring the flavour structure of the high-scale MSSM [PDF]
European Physical Journal C: Particles and Fields, 2020 We analyse the sensitivity of quark flavour-changing observables to the MSSM, in a regime of heavy superpartners. We analyse four distinct and motivated frameworks characterising the structure of the soft-breaking terms by means of approximate flavour ...

Electric Dipole Moments in The Limit of Heavy Superpartners [PDF]
Phys.Rev.Lett. 89 (2002) 101801, 2002 Supersymmetric loop corrections induce potentially large CP-violating couplings of the Higgs bosons to nucleons and electrons that do not vanish in the limit of heavy superpartners. The Higgs-mediated CP-odd four-fermion operators are enhanced by tan^3 beta and induce electric dipole moments of heavy atoms which exceed the current experimental bounds ...

Superpartner States in Quantum Mechanics of Colored Particle [PDF]
arXiv, 2003 Superpartner correspondence of states of colored particle in external chromomagnetic field given by non-commuting constant vector potentials is determined. Squared Dirac equation for this particle is solved exactly and explicit expressions of superpartner states are found. The wave functions of states with definite energy are found.

Electroweak superpartner production at 13.6 Tev with Resummino
European Physical Journal C: Particles and Fields, 2023 Due to the greater experimental precision expected from the currently ongoing LHC Run 3, equally accurate theoretical predictions are essential. We update the documentation of the Resummino package, a program dedicated to precision cross section ...

Superpartner Solutions of a BPS Monopole in Noncommutative Space [PDF]
Phys.Rev. D64 (2001) 087702, 2001 We construct U(2) BPS monopole superpartner solutions in N=2 non-commutative super Yang-Mills theory. Calculation to the second order in the noncommutative parameter $\theta$ shows that there is no electric quadrupole moment that is expected from the magnetic dipole structure of noncommtative U(2) monopole.

Fingerprints of supersymmetric spin and charge dynamics observed by inelastic neutron scattering [PDF]
Nature CommunicationsSupersymmetry is an algebraic property of a quantum Hamiltonian that, by giving every boson a fermionic superpartner and vice versa, may underpin physics beyond the Standard Model. Fractional bosonic and fermionic quasiparticles are familiar in condensed

A microscopic model for inflation from supersymmetry breaking [PDF]
European Physical Journal C: Particles and Fields, 2019 We have proposed recently a framework for inflation driven by supersymmetry breaking with the inflaton being a superpartner of the goldstino, that avoids the main problems of supergravity inflation, allowing for: naturally small slow-roll parameters ...

In the quest for a global (super)symmetry breaking mechanism: an extension of the vibronic mixing process to superpartners [PDF]
arXiv, 2008 We propose a global symmetry-breaking mechanism based on an extension of the vibronic (cooperative Jahn-Teller) effects (comprising electron-phonon superpartners) to generalize them into fermion-boson superpartners. Examples of superpairs are constructed by combining phonons, photons, pi-mesons, etc. with electrons, holes, nucleons, etc.
