"Big" Divisor D3/D7 Swiss Cheese Phenomenology

TL;DR

This paper reviews recent advances in Swiss Cheese Phenomenology involving D3 and D7 branes, focusing on large volume cosmology, supersymmetry breaking, and particle mass predictions within string theory frameworks.

Contribution

It provides a comprehensive review of how large volume scenarios can reconcile cosmology with particle phenomenology, including soft SUSY breaking and fermion mass generation.

Findings

Large volume cosmology and phenomenology are compatible.

Predicted fermion masses in the MeV-GeV range.

Indications of split SUSY scenarios.

Abstract

We review progress made over the past couple of years in the field of Swiss Cheese Phenomenology involving a mobile space-time filling D3-brane and stack(s) of fluxed D7-branes wrapping the "big" (as opposed to the "small") divisor in (the orientifold of a) Swiss-Cheese Calabi-Yau. The topics reviewed include reconciliation of large volume cosmology and phenomenology, evaluation of soft supersymmetry breaking parameters, one-loop RG-flow equations' solutions for scalar masses, obtaining fermionic (possibly first two generations' quarks/leptons) mass scales in the O(MeV-GeV)-regime as well as (first two generations') neutrino masses (and their one-loop RG flow) of around an eV. The heavy sparticles and the light fermions indicate the possibility of "split SUSY" large volume scenario.
