Phase-shift analysis of π−p → KmOΛ

Digital Binary Phase-shift Keyed Signal Detector

We have developed the effective algorithm for detecting digital binary phase-shift keyed signals. This algorithm requires a small number of arithmetic operations over the signal period. It can be relatively easy implemented based on the modern programmable logic devices. It also provides high interference immunity by identifying signal presence when signal-to-noise ratio is much less that its w...

Preliminary Results of a Phase Shift Analysis

I wish to present a summary on the recent work of the CERN-Heidelberg-Saclay collaboration. ' The data come from a systematic K-p bubble chamber investigation using the Saclay 81 cm HBC in a low momentum separated K-beam2 at the CERN P. S. An exposure of about 150,000 pictures (with hydrogen), were taken at 23 different momenta in the range of N 800-1200 MeV/c. The momentum values are shown in ...

Analysis of ππ phase shift σ - particle and “ repulsive core ”

In the previous work, analyzing the I=0 S-wave ππ-scattering phase-shift through a new method of Interfering Breit-Wigner amplitudes, we have shown possibility of existence of a light scalar, σ particle, by assuming a negative back-ground phaseshift, corresponding to “repulsive core” in ππ-interaction. In this work we investigate further, to what extent, σ-properties and size of core radius are...

Analysis of Differential Phase Shift Quantum Key Distribution

We review the implementation of two QKD protocols (BB84 and B92) keeping in mind that their implementations do not easily satisfy the requirement of use of single photons. We argue that current models do not take into account issues raised by the Uncertainty Principle related to time-location and transmission characteristics of single photons. This indicates that security proofs of current impl...
