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 implications of the many proper time amplitudes for the process Φ → K o + ¯ K o was discussed in a recent letter of B. Kayser and L. Stodolsky who predicted a small correction (∼ 5%) to the usually predicted phase oscillation frequency for forthcoming Φ factory experiments. Based on previous work (also using the many proper times formalism), we predicted a much larger correction factor ≈ 2....

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.

The understanding of the effects multidirectional loadings imposed on major load bearing elements such as reinforced concrete (RC) columns by seismic actions for collapse prevention is utmost importance, and a few simplified models are available in literature. In this study, distinguishing features two machine-learning (ML) methods, namely, multi expression programming (MEP) adaptive neuro-fuzz...

Rock failure generally leads to serious consequences, and it is significant obtain the precursor information prior using associated techniques. Thus, essential acquire probe relevant information. In this study, true triaxial tests are performed on red sandstone specimens under varying intermediate principal stress conditions. The thermal infrared image evolution temperature-induced change chara...

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.

The status of CP violation and the CKM matrix is reviewed. Direct CP violation in B decay has been established and the measurement of sin 2β in ψK modes reached 5% accuracy. I discuss the implications of these, and of the possible deviations of the CP asymmetries in b → s modes from that in ψK. The first meaningful measurements of α and γ are explained, together with their significance for cons...

Seafloor diking-eruptive events represent the irreducible, quantum events of upper oceanic crustal accretion. They record events by which a large portion of the oceanic crust has formed through geological history. Since 1993, the U.S. Navy's real-time Sound Surveillance System has allowed location of ongoing acoustic signatures of dike emplacement and basalt eruptions at ridge crests in the nor...
