On the MSSM with hierarchical squark masses and a heavier Higgs boson

TL;DR

This paper explores a supersymmetric model with a heavier Higgs boson and hierarchical squark masses, analyzing its naturalness, phenomenology at the LHC, and implications for Dark Matter.

Contribution

It proposes a natural realization of a spectrum with a heavy Higgs and heavy first-two-generation squarks, addressing naturalness and flavor issues in supersymmetry.

Findings

Heavy Higgs boson between 200-300 GeV compatible with the model

First two generations of squarks above 20 TeV to solve flavor problems

Phenomenological implications for LHC searches and Dark Matter constraints

Abstract

In the contest of supersymmetric extensions of the Standard Model, we consider a spectrum in which the lightest Higgs boson has mass between 200 and 300 GeV and the first two generations of squarks have masses above 20 TeV, considering the Higgs boson mass and the Supersymmetric Flavour Problem as related naturalness problems. After the analysis of some models in which the previous spectrum can be naturally realised, we consider the phenomenological consequences for the LHC and for Dark Matter.
