Fourth-generation SM imprints in B -> K^*l^+l^- decays with polarized K^*
Aqeel Ahmed, Ishtiaq Ahmed, M. Jamil Aslam +3
The implication of the fourth-generation quarks in the B -> K^*l^+l^- (l=mu,tau) decays, when K^* meson is longitudinally or transversely polarized, is presented. In this context,…
Analysis of B_{C} --> D_{s}^{*}l^{+}l^{-} in the Standard Model Beyond Third Generation
Ishtiaq Ahmed, M. Ali Paracha, M. Junaid +3
The weak decays of B_{c} --> D_{s}^{*}l^{+}l^{-} (l=mu,tau) are investigated in the Standard Model with fourth generation (SM4). Taking fourth generation quark mass m_{t'} of about…
Comparative Study of B_{c} --> D_{s}^{*}l^{+}l^{-} Decays in Standard Model and Supersymmetric Models
Aqeel Ahmed, Ishtiaq Ahmed, M. Ali Paracha +3
A comparative study of the exclusive rare () decays has been made in the minimal supersymmetric models (MSSM) and the SUS…
K_1(1270)-K_1(1400) mixing and the fourth generation SM effects in B-->K_1l^+l^- decays
Aqeel Ahmed, Ishtiaq Ahmed, M. Ali Paracha +1
The implications of the fourth generation quarks in the B-->K_{1}(1270,1400)l^{+}l^{-} with l=mu, tau decays are studied, where the mass eigenstates K_{1}(1270) and K_{1}(1400) are…
Semileptonic charmed meson decays in Universal Extra Dimension Model
M. Ali Paracha, Ishtiaq Ahmed, M. Jamil Aslam
Form factors parameterizing the semileptonic decay () are calculated using the frame work of Ward Identities. These form factors ar…
