The effects of polarization on the observables in the decay $Ξ_{cc}^{++} \to Ξ_{c}^{+} ℓ ˉ ν_{ℓ}$

Qazi Maaz Us Salam, Anamta Asif, Ishtiaq Ahmed +1

We investigate the effects of polarization on several physical observables in the semileptonic decay $Ξ_{cc}^{++} \to Ξ_{c}^{+} ℓ ˉ ν_{ℓ}$ . We analyze the polarizati…

Chirality structure of vector like new physics operators in charged current transitions

Sajawal Zafar, Qazi Maaz Us Salam, Rana Khan +2

We investigate the cascade decay $B_{s}^{* 0} \to D_{s}^{-} (\to τ^{-} ν ˉ_{τ}) ℓ^{+} ν_{ℓ}$ induced by flavor changing charged currents in the context of the Standa…

LHC and dark matter implications of t-b-τ Yukawa unification in split SUSY GUTs

Mureed Hussain, Rizwan Khalid, Cem Salih Un

We investigate a grand unification (GUT) inspired version of the minimal supersymmetric standard model (MSSM) based on a left-right symmetric $4$ - $2$ - $2$ gauge group, incorporating…

Investigating New Physics through the Observables of Semileptonic $B_{s} \to K^{*} (\to K π) μ^{+} μ^{-}$ Decay

Zohaib Aarfi, Qazi Maaz Us Salam, Ishtiaq Ahmed +3

The rare four-fold decay $B_{s} \to K^{*} (\to K π) μ^{+} μ^{-}$ , governed by the flavor-changing neutral current transition $b \to d μ^{+} μ^{-}$ , provides a sensitive probe for testing the Standa…

Exploring New Physics in transition $b \to s ℓ^{+} ℓ^{-}$ through different $B_{c} \to D_{s}^{(*)} ℓ^{+} ℓ^{-}$ observables

Qazi Maaz Us Salam, Ishtiaq Ahmed, Rizwan Khalid +1

Inspired by the discrepancies observed in the $b \to s ℓ^{+} ℓ^{-}$ neutral current decays, we study the decay channel $B_{c} \to D_{s}^{(*)} ℓ^{+} ℓ^{-}$ ( $ℓ = μ, τ$ ), which is ba…

Yukawa Unification with light supersymmetric particles consistent with LHC constraints

Mureed Hussain, Rizwan Khalid

We investigate supersymmetric models with left-right symmetry based on the group $S U (4)_{c} \times S U (2)_{L} \times S U (2)_{R}$ ( $4$ - $2$ - $2$ ) with negative sign of bilinear Higgs po…
