“…In all cases ∆ is minimal near M higgs ≈ 115 GeV. For ways to have M higgs ≈ 125 − 130 GeV with smaller fine-tuning ∆ ≈ O(10) in SUSY models see [1,[27][28][29][30][31][32][33][34][35][36].…”

“…We let the reader to make his own opinion, based on the above results and figures and also on future LHC data (on gluino, higgs, stop and m susy ) whose updated impact on our ∆ can easily be obtained. Also it should be kept in mind that very simple new physics beyond these SUSY models (like CMSSM with a gauge singlet with a TeV-scale SUSY mass term or a massive U(1) ′ ) can lead to a very acceptable ∆ ≈ O(10) for a higgs mass as large as 130 GeV [27][28][29][30][31][32][33][34][35][36]. Further, subjective criteria also exist in other approaches that compare the probability of various models, such as those based on the Bayesian approach.…”

We provide a comparative study of the fine tuning amount (∆) at the two-loop leading log level in supersymmetric models commonly used in SUSY searches at the LHC. These are the constrained MSSM (CMSSM), non-universal Higgs masses models (NUHM1, NUHM2), non-universal gaugino masses model (NUGM) and GUT related gaugino masses models (NUGMd). Two definitions of the fine tuning are used, the first (∆ max ) measures maximal fine-tuning w.r.t. individual parameters while the second (∆ q ) adds their contribution in "quadrature". As a direct consequence of two theoretical constraints (the EW minimum conditions), fine tuning (∆ q ) emerges at the mathematical level as a suppressing factor (effective prior) of the averaged likelihood (L) under the priors, under the integral of the global probability of measuring the data (Bayesian evidence p(D)). For each model, there is little difference between ∆ q , ∆ max in the region allowed by the data, with similar behaviour as functions of the Higgs, gluino, stop mass or SUSY scale (m susy = (mt 1 mt 2 ) 1/2 ) or dark matter and g−2 constraints. The analysis has the advantage that by replacing any of these mass scales or constraints by their latest bounds one easily infers for each model the value of ∆ q , ∆ max or vice versa. For all models, minimal fine tuning is achieved for M higgs near 115 GeV with a ∆ q ≈ ∆ max ≈ 10 to 100 depending on the model, and in the CMSSM this is actually a global minimum. Due to a strong (≈ exponential) dependence of ∆ on M higgs , for a Higgs mass near 125 GeV, the above values of ∆ q ≈ ∆ max increase to between 500 and 1000. Possible corrections to these values are briefly discussed.

“…Within this class of models, additional operators are generated when SUSY and the R-symmetry are broken in the hidden sector and the effects are mediated to the observable sector through Planck-suppressed operators. Alternatively, one may generalize the MSSM by introducing effective dimension four and five operators [30][31][32]. These operators can reduce the amount of fine tuning in the scalar sector and be sensitive to new degrees of freedom at the TeV scale.…”

Abstract:The minimal extension of the MSSM (NMSSM) has been widely studied in the search for a natural solution to the µ-problem. In this work, we consider a variation of the NMSSM where an additional singlet is added and a Peccei-Quinn symmetry is imposed. We study its neutralino sector and compute the annihilation cross section of the lightest neutralino. We use existent cosmological and collider data to constrain the parameter space and consider the lightest neutralino, with mass between 1 and 15 GeV, as a thermal dark matter candidate.

“…A case in mind is the Higgs sector of the BMSSM [20][21][22][23][24][25] which is a general effective Lagrangian approach to the MSSM first introduced to address the naturalness problem [26,27]. Masses up to 250 GeV can be naturally achieved for the lightest Higgs of the model [28][29][30][31][32][33]. Most recent analyses of the model taking into account ATLAS and CMS data now only allow masses below 140 GeV for the lightest Higgs [32,33].…”

Beyond the MSSM Higgs bosons at 125 GeV

Beyond the MSSM framework is an effective theory approach that encapsulates a variety of extensions beyond the MSSM with which it shares the same field content. The lightest Higgs mass can be much heavier than in the MSSM without creating a tension with naturalness or requiring superheavy stops. The phenomenology of the Higgs sector is at the same time much richer. We critically review the properties of a Higgs with mass around 125 GeV in this model. In particular, we investigate how the rates in the important inclusive 2 channel, the 2 þ 2 jets and the ZZ ! 4l (and/or WW) can be enhanced or reduced compared to the standard model and what kind of correlations between these rates are possible. We consider both a vanilla model where stops have moderate masses with no trilinear stop mixing term and a model having a large stop mixing with a light stop. We show that in both cases there are scenarios that lead to enhancements in these rates at a mass of 125 GeV corresponding to either the lightest Higgs or the heaviest CP-even Higgs of the model. In all of these scenarios we study the prospects of finding other signatures of either the 125 GeV Higgs or those of the heavier Higgses. In most cases the " channels are the most promising. Exclusion limits from the recent LHC Higgs searches are folded in our analyses while the tantalizing hints for a Higgs signal at 125 GeV are used as an example of how to constrain beyond the MSSM and/or direct future searches.
