We explore corrections to electroweak parameters in the context of Extended Technicolor (ETC) models in which the ETC gauge-boson which generates the top-quark mass carries weak SU(2) charge. For mt ∼ 150 GeV there exist potentially large corrections to the Z decay width to b-quarks. Interestingly, in contrast to the situation in ETC models where the gauge-boson which generates the top-quark ma...

The P-decay of cosmic-ray mesons is discussed. The possible process of decay into electron-neutrino plus a neutral particle is treated in some detail. This process is found to fit in well with the familiar formalism of P-decay of atomic nuclei. A comparison is made with present experimental data on mesons.

As we are transitioning to an energy system based on renewable sources, the atmosphere is becoming one of our primary sources. Understanding atmospheric flows through wind farms has become issue large economic and societal concern.

Non-leptonic D meson decays may provide a reliable testbed for the multiquark interpretation of light scalar mesons. In this letter we consider D s decay and show that a 4-quark f 0 (980) meson could induce a decay pattern, which is forbidden for a q ¯ q constituent structure. Experimental tests to probe such possibilities are within reach in the near future.

We examine the charmless hadronic B decay modes in the context of R-parity violating (Rp / ) supersymmetry. We try to explain the large branching ratio (compared to the Standard Model (SM) prediction) of the decay B → ηK. There exist data for other observed η(′) modes and among these modes, the decay B0 → ηK∗0 is also found to be large compared to the SM prediction. We investigate all these mod...

We describe experimental results on the Gamow-Teller strength distribution as obtained from the B-decay of exotic nuclei. The most complete results, in light nuclei, confirm the absence of strength noted in (p,n) measurements. In heavier nuclei it is the remote tail of the resonance that is established by 8-decay.
