“…In a hidden sector based supergravity type of model these interactions are typically suppressed by the scale of mediation [74]. Similar to the past analyses [66][67][68][69][70][71][72][73][80][81][82][83], in this work, without imposing any model-dependent restrictions, we treat such soft breaking at par with all the standard MSSM soft interactions 3 .…”

“…In contrast to the above analyses that had to manage the flavor issues carefully and are strongly constrained by µ → eγ or may have to live with light SUSY spectra or very large tan β, we focus on including nonstandard soft terms. Non-holomorphic trilinear terms may be augmented with MSSM leading to the so-called Non-holomorphic Supersymmetric Standard Model (NHSSM) [66][67][68][69][70][71][72][73][74]. The above terms are soft and may be included in a SUSY model if there is no gauge singlet.…”

“…Some of the early mentions/works may be seen in Refs. [74][75][76][77][78][79], whereas a number of phenomenological analyses may be seen here [66][67][68][69][70][71][72][73][80][81][82][83][84]. Our work would not demand any super large µ, or light spectra and we will use a flavor friendly scenario of identical slepton masses for the first two generations with equal coefficients for the left and right mass parameters.…”

The recent Fermilab muon g − 2 result and the same for electron due to fine-structure constant measurement through 133 Cs matter-wave interferometry are probed in relation to MSSM with non-holomorphic (NH) trilinear soft SUSY breaking terms, referred as NHSSM. Supersymmetric contributions to charged lepton (g − 2) l can be enhanced via the new trilinear terms involving a wrong Higgs coupling with left and right-handed scalars. Bino-slepton loop is used to enhance the SUSY contribution to g − 2 where wino mass stays at 1.5 TeV and the left and right slepton mass parameters for the first two generations are considered to be the same. Unlike many MSSM based analyses, the model does not require a light electroweakino, or light sleptons, or unequal left and right slepton masses, or a very large higgsino mass parameter. First part of the analysis involves (g − 2) µ constraint along with limits from Higgs mass, B-physics, collider data, direct detection of dark matter (DM) while focusing on a higgsino DM which is underabundant in nature. We then impose the constraint from electron g − 2 where a large Yukawa threshold corrections (an outcome of NHSSM) and opposite signs of trilinear NH coefficients associated with µ and e fields are used to satisfy the dual limits of ∆a µ and ∆a e (where the latter comes with negative sign).Varying Yukawa threshold corrections further provide the necessary flavor-dependent enhancement of ∆a e /m 2 e compared to that of ∆a µ /m 2 µ . A larger Yukawa threshold correction through A e for y e also takes away the direct proportionality of a e with respect to tan β. With a finite intercept, a e becomes only an increasing function of tan β. We identified the available parameter space in the two cases while also applying the ATLAS data on slepton pair production in the plane of slepton mass parameter and the mass of the lightest neutralino.

“…Analyses of Refs. [39][40][41][42][43][44][45][46][47][48] used renormalization group evolutions within a Constrained MSSM (CMSSM [9]) like setup. Here the NH parameters were considered to be of unknown origin and were at par with other CMSSM mass and trilinear parameters.…”

The recent Fermilab muon $$g-2$$ g - 2 result and the same for electron due to fine-structure constant measurement through $${}^{133}\textrm{Cs}$$ 133 Cs matter-wave interferometry are probed in relation to MSSM with non-holomorphic (NH) trilinear soft SUSY breaking terms, referred to as NHSSM. Supersymmetric contributions to charged lepton $$(g-2)_l$$ ( g - 2 ) l can be enhanced via the new trilinear terms involving a wrong Higgs coupling with left and right-handed scalars. Bino-slepton loop is used to enhance the SUSY contribution to $$g-2$$ g - 2 where wino mass stays at 1.5 TeV and the left and right slepton mass parameters for the first two generations are considered to be the same. Unlike many MSSM-based analyses completed before, the model does not require a light electroweakino, or light sleptons, or unequal left and right slepton masses, or a very large higgsino mass parameter. In absence of popular UV complete models, we treat the NH terms at par with MSSM soft terms, in a model independent framework of Minimal Effective Supersymmetry. The first part of the analysis involves the study of $$(g-2)_\mu $$ ( g - 2 ) μ constraint along with the limits from Higgs mass, B-physics, collider data, direct detection of dark matter (DM), while focusing on a higgsino DM which is underabundant in nature. We then impose the constraint from electron $$g-2$$ g - 2 where a large Yukawa threshold correction (an outcome of NHSSM) and opposite signs of trilinear NH coefficients associated with $$\mu $$ μ and e fields are used to satisfy the dual limits of $$\Delta {a_\mu }$$ Δ a μ and $$\Delta {a_e}$$ Δ a e (where the latter comes with negative sign). Varying Yukawa threshold corrections further provide the necessary flavor-dependent enhancement of $$\Delta {a_e}/m_e^2$$ Δ a e / m e 2 compared to that of $$\Delta {a_\mu }/m_\mu ^2$$ Δ a μ / m μ 2 . A larger Yukawa threshold correction through $$A^\prime _e$$ A e ′ for $$y_e$$ y e also takes away the direct proportionality of $$a_e$$ a e with respect to $$\tan \beta $$ tan β . With a finite intercept, $$a_e$$ a e becomes only an increasing function of $$\tan \beta $$ tan β . We identified the available parameter space in the two cases while also satisfying the ATLAS data from slepton pair production searches in the plane of slepton mass parameter and the mass of the lightest neutralino.
