The goal of the DIRAC experiment at CERN is to measure with high precision the lifetime of the $\pi^+\pi^-$ atom ($A_{2\pi}$), which is of order $3\times10^{-15}$ s, and thus to determine the s-wave $\pi\pi$-scattering lengths difference $|a_{0}-a_{2

Publikováno v: Proceedings. 9th IEEE Workshop on Signal Propagation on Interconnects, 2005..

In this paper a sandwich multilayer structure as a model of a mixed-signal systems (digital and analog) interconnect is introduced. The method for analysis in frequency domain of such inhomogenous structure based on matrix functions is presented. The

The DIRAC experiment aims to measure the lifetime of π+π− atoms in the ground state with 10% precision, using the 24 GeV/c proton beam of the CERN Proton Synchrotron. As the value of the above lifetime of order 10−15s is dictated by a strong in
