Jets and QCD: A Historical Review of the Discovery of the Quark and Gluon Jets and its Impact on QCD
Ahmed Ali, Gustav Kramer
The observation of quark and gluon jets has played a crucial role in establishing Quantum Chromodynamics [QCD] as the theory of the strong interactions within the Standard Model of…
Implication of the Branching Ratios for the CKM Phenomenology
A. Ali, E. Lunghi, A. Ya. Parkhomenko
We study the implication of the recent measurement by the BELLE collaboration of the averaged branching fraction $\bar B_{exp} [B \to (ρ, ω) γ] = (1.8^{+0.6}_{-0.5} \pm 0.1) \times…
A Comparative Study of the Decays in Standard Model and Supersymmetric Theories
A. Ali, Patricia Ball, L. T. Handoko +1
Using improved theoretical calculations of the decay form factors in the Light Cone-QCD sum rule approach, we investigate the decay rates, dilepton invariant mass spectra and the f…
Experimental Tests of Factorization in Charmless Non-Leptonic Two-Body B Decays
A. Ali, G. Kramer, C. D. Lu
Using a theoretical framework based on the next-to-leading order QCD-improved effective Hamiltonian and a factorization Ansatz for the hadronic matrix elements of the four-quark op…
Photon Energy Spectrum in and Comparison with Data
A. Ali, C. Greub
A comparison of the inclusive photon energy spectrum in the radiative decay $\BGAMAXS$, measured recently by the CLEO collaboration, with the standard model is presented, using a $…
Towards a Model Independent Analysis of Rare Decays
Ahmed Ali, Gian Giudice, Thomas Mannel
We propose to undertake a model-independent analysis of the inclusive decay rates and distributions in the processes \bgamaxs~ and \Bsell ~( or ). We show how measu…
Towards a Model-Independent Analysis of Rare Decays
A. Ali, G. F. Giudice, T. Mannel
Motivated by the experimental accessibility of rare decays in the ongoing and planned experiments, we propose to undertake a model-independent analysis of the inclusive decay r…
