pMSSM versus complete models and the excellent prospects for top-squark discovery at HL-LHC

Journal of High Energy Physics
LHC supersymmetric (SUSY) particle search limits are usually performed within the context of simplified models and subsequently interpreted within the 19 parameter phenomenological MSSM (pMSSM) as to how many models avoid search limits for a particular ...

Constraining the four-light quark operators in the SMEFT with multijet and VBF processes at linear level

Journal of High Energy Physics
We investigate how the interference of the SM with ten four-light quark operators in the SMEFT can be constrained thanks to multijet and Z, W, γ VBF production in association with jets.

Scalar resonances near 650 and 95 GeV in the GNMSSM with correct dark matter relic abundance

Journal of High Energy Physics
Recent CMS analyses report an excess in the diphoton-plus- b b ¯ $$ b\overline{b} $$ channel, indicative of a heavy resonance around 650 GeV decaying into a Standard Model (SM)-like Higgs boson and a lighter scalar near 95 GeV.

Searches for power-law warped extra dimensions

Journal of High Energy Physics
Extra dimensions with a bulk dilaton field can be power-law warped, unlike the exponential warping in the Randall-Sundrum (RS) model. We show that this mildly warped extra dimension can address the hierarchy problem with a novel Kaluza-Klein (KK ...

Revisiting universal extra-dimension model with gravity mediated decays

Journal of High Energy Physics
We explore the collider phenomenology of the fat-brane realization of the Minimal Universal Extra Dimension (mUED) model, where Standard Model (SM) fields propagate in a small extra dimension while gravity accesses additional large extra dimensions. This

Textures of neutrino mass matrix from S 4-flavor symmetry

Journal of High Energy Physics
We study a texture of neutrino mass matrix characterized by two constraints consisting of one equality and another antiequality between two elements corresponding to two pairs of the matrix entries.

Drell-Yan bounds on gapped continuum spectra

Journal of High Energy Physics
Theories with gapped continuum spectra have gotten some attention, either as pure 4D models like unparticles, or in 5D realizations as certain soft walls constructions. In this paper, we derive experimental bounds from Drell-Yan processes (pp → ℓ + ℓ − ,

The SM expected branching ratio for h → γγ and an excess for h → Zγ

Journal of High Energy Physics
The recent measurements of h → Zγ from ATLAS and CMS show an excess of the signal strength μ Z = σ · B obs / σ · B SM $$ {\left(\sigma \cdotp \mathcal{B}\right)}_{\textrm{obs}}/{\left(\sigma \cdotp \mathcal{B}\right)}_{\textrm{SM}} $$ = 2.2 ± 0.7 ...
