Measurement of the Running of the Electromagnetic Coupling at LEP
The study of low-angle and large-angle Bhabha scattering at LEP gives access to the running of the electromagnetic coupling. Two recent measurements of the OPAL and L3 collaborations probe the running of α in the regions 1.8 GeV < −Q < 6.1 GeV and 1800 GeV < −Q < 21600 GeV, respectively. The strategies and the results of these studies are presented. A global overview is given of the agreement o...
متن کاملOn the running electromagnetic coupling constant at MZ
We present a discussion on how to define the running electromagnetic coupling constant at MZ or some other intermediate scale as e.g. mΥ. We argue that a natural definition consistent with general requirements of the renormalization group should be based on Euclidean values of the momentum of the photon propagator as the appropriate scale. We demonstrate in an explicit example of evaluating the...
متن کاملMeasurements of the Running of the Electromagnetic Coupling at LEP
The study of Bhabha scattering at ee colliders probes the running of the electromagnetic coupling. After early measurements by the VENUS collaboration at TRISTAN and the by L3 collaboration at LEP, two recent analyses have been performed by the OPAL and L3 collaborations. The OPAL collaboration studied highstatistics low-angle Bhabha scattering at LEP, achieving a precise determination of the r...
متن کاملMixed Circuit/Electromagnetic Analysis of Field Coupling to High Speed Interconnects In Inhomogenous Medium
An efficient method is presented for rigorous analysis of incident field coupling to high speed interconnects. The method is based on generating time domain equivalent sources from incoming fields through finite difference time domain analysis (FDTD) and incorporating them with a circuit level simulator such as SPICE. With this approach, it is possible to perform a circuit analysis of arbitrari...
