Projecting on a suitable subset of coordinates, a picture is constructed in which the conformal boundary of AdS 5 × S 5 and those of the plane wave resulting in the Penrose limit is located at the same line. All AdS 5 × S 5 and plane wave geodesics are classified in their integrated form. Performing the Penrose limit the approach of null geodesics reaching the conformal boundary of AdS 5 × S 5 ...

We explore the S-wave and P-wave amplitudes for NNK and ΛΛK interactions using chiral perturbation theory to O(m s log m s). In contrast to the large corrections found in P-wave amplitudes in the nonleptonic decay of octet baryons, the NNK amplitudes receive only small corrections to their tree-level values. The uncertainty in the ΛΛK amplitudes is found to be large.

It is shown that the wave function describes the state of the statistical ensemble E [S] of individual particles, or the statistical average particle 〈S〉. This result follows from the fact that in the classical limit h̄ = 0 the Schrödinger equation turns to the dynamic equations for the statistical ensemble of classical particles. The idea that the wave function describes the state of an individ...

The peculiarities in tunneling characteristics have been studied in the light of the controversy between s-wave and d-wave character of High Tc superconductivity. We show that anisotropic s-wave gap has the same low voltage power law conductance and two peak structure in the density of states as d-wave superconductors. The assymetric tunneling conductance and zero bias conductance for the c-axi...

Radiative decays of heavy baryons are analyzed within the Heavy Quark Symmetry (HQS). It is shown that employing the light-diquark symmetries, the number of electromagnetic couplings among S-wave and P-wave states as well as those between P-wave to S-wave transitions can be reduced significantly. Using this constituent quark model picture the phenomenological implications of some of these decay...

We compute S-wave and P-wave electromagnetic quarkonium decays at order v7 in the heavy-quark velocity expansion. In the S-wave case, our calculation confirms and completes previous findings. In the P-wave case, our results are in disagreement with previous ones; in particular, we find that two matrix elements less are needed. The cancellation of infrared singularities in the matching procedure...

Receiver function is defined as the spectral ratio of the radial component and the vertical component of the ground motion. It is used to characterize converted waves. We extend the use of the receiver function to downhole data using waves recorded in a borehole, excited by an earthquake of magnitude 4.0 near San Francisco, California, on 26 June 1994. The focal depth of the event was 6.6 km an...
