Title: Impact of an extra gauge interaction on naturalness of supersymmetry

Abstract

It is pointed out that in supersymmetric models with a new gauge symmetry under which the Higgs is charged, the fine-tuning of the electroweak symmetry breaking is relaxed due to suppression of the top Yukawa coupling at higher scales by a new large gauge coupling. Here, we calculate the fine-tuning in an explicit model and find that the lower bounds on stops and gluino masses from the naturalness criterion are increased by several hundred GeV in comparison to the Minimal Supersymmetric Standard Model (MSSM). The fine-tuning is improved by one to two orders of magnitude as compared to the MSSM, as a consequence of both the suppression of the top Yukawa coupling and the additional tree-level contribution to the Higgs mass allowing for much lighter stops.

Little Supersymmetry and the Supersymmetric Little Hierarchy Problem

Journal Article Birkedal, Andreas ; Chacko, Z ; Gaillard, Mary K - Journal of High Energy Physics

The current experimental lower bound on the Higgs mass significantly restricts the allowed parameter space in most realistic supersymmetric models, with the consequence that these models exhibit significant fine-tuning. We propose a solution to this `supersymmetric little hierarchy problem'. We consider scenarios where the stop masses are relatively heavy - in the 500 GeV to a TeV range. Radiative stability of the Higgs soft mass against quantum corrections from the top quark Yukawa coupling is achieved by imposing a global SU(3) symmetry on this interaction. This global symmetry is only approximate - it is not respected by the gauge interactions. A subgroup of the global symmetry is gauged by the familiar SU(2) of the Standard Model. The physical Higgs is significantly lighter than the other scalars because it is the pseudo-Goldstone boson associated with the breaking of this symmetry. Radiative corrections to the Higgs potential naturally lead to the right pattern of gauge and global symmetry breaking. We show that both the gauge and global symmetries can be embedded into a single SU(6) grand unifying group, thereby maintaining the prediction of gauge coupling unification. Among the firm predictions of this class of models are new states with the quantum numbers of 10 andmore »« less

MSSM from Scherk-Schwarz supersymmetry breaking

Journal Article Diego, D ; Gersdorff, G v ; Quiros, M - Physical Review. D, Particles Fields

We present a five-dimensional model compactified on an interval where supersymmetry is broken by the Scherk-Schwarz mechanism. The gauge sector propagates in the bulk, two Higgs hypermultiplets are quasilocalized, and quark and lepton multiplets localized, in one of the boundaries. The effective four-dimensional theory is the MSSM with very heavy gauginos, heavy squarks, and light sleptons and Higgsinos. The soft tree-level squared masses of the Higgs sector can be negative and they can (partially) cancel the positive one-loop contributions from the gauge sector. Electroweak symmetry breaking can then comfortably be triggered by two-loop radiative corrections from the top-stop sector. Themore »« less

Two exercises in supersymmetry: a low-energy supergravity model and free string field theory

Technical Report Preitschopf, C R

The new features of a supersymmetric standard model in the presence of heavy families are studied. The minimal set of Higgs fields, the desert between the electroweak and the grand unification scale and perturbative values of the dimensionless parameters throughout this region are assumed. Using the numerical as well as the approximate analytic solution of the renormalization group equations, the evolution of all the parameters of the theory are studied in the case of large Yukawa couplings for the fourth family. The desired spontaneous symmetry breaking of the electroweak symmetry takes place only for a rather unnatural choice of themore »« less

Can multi-TeV (top and other) squarks be natural in gauge mediation?

Journal Article Agashe, Kaustubh - Physical Review. D, Particles Fields

We investigate whether multi-TeV (1-3 TeV) squarks can be natural in models of gauge-mediated SUSY breaking. The idea is that for some boundary condition of the scalar (Higgs boson and top squark) masses, the Higgs boson (mass){sup 2}, evaluated at the renormalization scale {approx}O(100) GeV, is not very sensitive to (boundary values of) the scalar masses (this has been called ''focusing'' in recent literature). Then, the top squark masses can be multi-TeV without leading to fine-tuning in electroweak symmetry breaking. Minimal gauge mediation does not lead to this focusing (for all values of tan {beta} and the messenger scale): themore »« less
