In grand unified theories (GUT), non-universal boundary conditions for the gaugino masses may arise at the unification scale, and affect the observability of the neutral MSSM Higgs bosons (h/H/A) at the LHC. The implications of such non-universal gaugino masses are investigated for the Higgs boson production in the SUSY cascade decay chaing →qq,q →χ2q,χ2 →χ1h/H/A, h/H/A → bb produced in pp interactions. In the singlet representation with universal gaugino masses only the light Higgs boson can be produced in this cascade with the parameter region of interest for us, while with non-universal gaugino masses heavy neutral MSSM Higgs boson production may dominate. The allowed parameter space in the light of the WMAP constraints on the cold dark matter relic density is investigated in the above scenarios for gaugino mass parameters. We also demonstrate that combination of representations can give the required amount of dark matter in any point of the parameter space. In the non-universal case we show that heavy Higgs bosons can be detected in the studied cascade in parameter regions with the WMAP preferred neutralino relic density.

“…Results in case of tan β = 2 are plotted for the several values of θ in figure 1. 5 In the left panel we plot 5 There is U(1)x D-term contribution to the soft scalar masses such as (m Dx f ) 2 g 2 x Q f QS S 2 , where S determines a U(1)x breaking scale. Since we fix S as S = 1.5 TeV and then Mx > gx S is satisfied in the almost all regions of the large Mx, this contribution is neglected in this calculation.…”

We present a SUSY breaking scenario based on Abelian gaugino kinetic term mixings between hidden and observable sectors. If an extra U(1) gaugino in the observable sector obtains a large mass through this mixing effect based on SUSY breaking in the hidden sector, soft SUSY breaking parameters in the MSSM may be affected by radiative effects due to this gaugino mass. New phenomenological aspects are discussed in such a SUSY breaking scenario.

“…Thus different non-universalities lead to different kind of LSP scenarios. Some recent papers has partly grabbed the impact of non-universality feature in either minimal or non-minimal version of models in the context of dark matter search, see for example [10,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30].…”

We perform a comprehensive study of SU(5), SO(10) and E(6) supersymmetric GUT models where the gaugino masses are generated through the F-term breaking vacuum expectation values of the non-singlet scalar fields. In these models the gauginos are nonuniversal at the GUT scale unlike in the mSUGRA scenario. We discuss the properties of the LSP which is stable and a viable candidate for cold dark matter. We look for the GUT scale parameter space that leads to the the lightest SM like Higgs mass in the range of 122-127 GeV compatible with the observations at ATLAS and CMS, the relic density in the allowed range of WMAP-PLANCK and compatible with other constraints from colliders and direct detection experiments. We scan universal scalar (m G 0 ), trilinear coupling A 0 and SU(3) C gaugino mass (M G 3 ) as the independent free parameters for these models. Based on the gaugino mass ratios at the GUT scale, we classify 25 SUSY GUT models and find that of these only 13 models satisfy the dark matter and collider constraints. Out of these 13 models there is only one model where there is a sizeable SUSY contribution to muon (g−2).
