Supersymmetric Hybrid Inflation in Light of CMB Experiments and Swampland Conjectures

Waqas Ahmed, Shabbar Raza

This study revisits supersymmetric (SUSY) hybrid inflation in light of CMB experiments and swampland conjectures. We first show that if one adds radiative, soft mass, and SUGRA cor…

Probing the Supersymmetric Grand Unified Theories with Gravity Mediation at the Future Proton-Proton Colliders and Hyper-Kamiokande Experiment

Waqas Ahmed, Tianjun Li, Shabbar Raza

With the grand desert hypothesis, we have proposed to probe the supersymmetric Grand Unified Theories (GUTs) at the future proton-proton (pp) colliders and Hyper-Kamiokande experim…

A Comprehensive Study of Energy Dependence of Particle Ratios in $pp$ Collisions from SPS to LHC Energies

A. M. Khan, M. U. Ashraf, Junaid Tariq +2

A comprehensive study has been performed to estimate the kaon to pion ( $K^{\pm}$ / $π^{\pm}$ ) yield ratio and total kaon to total pion ( $K$ / $π$ ) yield ratio as a function of centre of ma…

Probing Relatively Heavier Right-Handed Selectron at the CEPC, $FC C_{ee}$ and ILC

Waqas Ahmed, Imtiaz Khan, Tianjun Li +2

We employ the low energy Minimal Supersymmetric Standard Model (MSSM) to explore the parameter space associated with $Z$ -pole and Higgs-pole solutions. Such parameter spaces can no…

Observability of triple top quark signal at Future Hadron Colliders

Ijaz Ahmed, Nazima Bi, M. S. Amjad

This paper is devoted to the Standard Model cross-sections for the production of single top, top quark in pairs, triple-top quarks, and four top-quarks at three different centre of…

The Natural Explanation of the Muon Anomalous Magnetic Moment via the Electroweak Supersymmetry from the GmSUGRA in the MSSM

Waqas Ahmed, Imtiaz Khan, Jinmian Li +3

The Fermi-Lab Collaboration has announced the results for the measurement of muon anomalous magnetic moment. Combining with the previous results by the BNL experiment, we have $4.2…

Sparticle Spectroscopy and Dark Matter in a $U (1)_{B - L}$ extension of MSSM

Waqas Ahmed, Shabbar Raza, Qaisar Shafi +2

We consider a class of SUSY models in which the MSSM gauge group is supplemented with a gauged $U (1)_{B - L}$ symmetry and a global $U (1)_{R}$ symmetry. This extension introduces onl…

Probing the Supersymmetric Grand Unified Theories at the Future Proton-Proton Colliders and Hyper-Kamiokande Experiment

Waqas Ahmed, Tianjun Li, Shabbar Raza +1

Gauge coupling unification in the Supersymmetric Standard Models strongly implies the Grand Unified Theories (GUTs). With the grand desert hypothesis, we show that the supersymmetr…

Pair production of heavy charged gauge bosons in $pp$ collisions at LHC

Ijaz Ahmed, Fazal Khaliq, M. U. Ashraf +2

Two opposite charged new heavy gauge boson pair production at the Large Hadron Collider (LHC) is presented in this paper. These bosons are known as $W^{^{'}}$ boson due to the reason…

The PeV-Scale Split Supersymmetry from Higgs Mass and Electroweak Vacuum Stability

Waqas Ahmed, Adeel Mansha, Tianjun Li +3

The null results of the LHC searches have put strong bounds on new physics scenario such as supersymmetry (SUSY). With the latest values of top quark mass and strong coupling, we s…

$b - τ$ Yukawa Unification in SUSY SU(5) with Mirage Mediation: LHC and Dark Matter Implications

Shabbar Raza, Qaisar Shafi, Cem Salih Un

We consider a class of $b - τ$ Yukawa unified Supersymmetric (SUSY) $S U (5)$ GUTs, in which the asymptotic gaugino $M_{1, 2, 3}$ masses are generated through a combination of gravity an…

Status of Natural Supersymmetry from the GmSUGRA in Light of the current LHC Run-2 and LUX data

Waqas Ahmed, Xiao-Jun Bi, Tianjun Li +4

We study natural supersymmetry in the Generalized Minimal Supergravity (GmSUGRA). For the parameter space with low energy electroweak fine-tuning measures less than 50, we are left…

Low Fine Tuning in Yukawa-deflected Gauge Mediation

Waqas Ahmed, Lorenzo Calibbi, Tianjun Li +2

We discuss a class of models with gauge-mediated supersymmetry breaking characterized by a non-unified messenger sector inducing non-standard gaugino mass ratios, as well as by add…

Analysis of Forward-Backward and Lepton Polarization Asymmetries in $B \to K_{1} ℓ^{+} ℓ^{-}$ Decays in the Two-Higgs-doublet Model

Naveed Ahmed, Ishtiaq Ahmed, M. Jamil Aslam

The exclusive semileptonic $B \to K_{1} (1270) ℓ^{+} ℓ^{-}$ ( $ℓ = μ, τ$ ) decays are analyzed in variants of two Higgs double models (THDMs). The mass eigenstates $K_{1} (1270)$ …
