We discuss the Cherenkov process ν → νγ in the presence of a homogeneous magnetic field. The neutrinos are taken to be massless with only standard-model couplings. The magnetic field fulfills the dual purpose of inducing an effective neutrino-photon vertex and of modifying the photon dispersion relation such that the Cherenkov condition ω < |k| is fulfilled. For a field strength Bcrit = m 2 e/e...
An example of discontinuity of the energy-momentum tensor moving at superluminal velocity is discussed. It is shown that the gravita-tional Mach cone is formed. The power spectrum of the corresponding Cherenkov radiation is evaluated.
It is shown that Cherenkov radiation can be observed at TESLA in electron collisions with optical laser pulses. The prospects for it to be observed at SLC, LEP, LHC and RHIC are discussed. The conclusions are compared with results for pair production. The problem of very high energy charged particles collisions with laser beams is widely discussed now, mostly in connection with the e + e −-pair...
Large liquid-scintillator-based detectors have proven to be exceptionally effective for low energy neutrino measurements due to their good energy resolution and scalability to large volumes. The addition of directional information using Cherenkov light and fast timing would enhance the scientific reach of these detectors, especially for searches for neutrino-less double-beta decay. In this pape...
The transverse dynamics of a 28.5-GeV electron beam propagating in a 1.4 m long, (0-2)x10(14) cm(-3) plasma are studied experimentally in the underdense or blowout regime. The transverse component of the wake field excited by the short electron bunch focuses the bunch, which experiences multiple betatron oscillations as the plasma density is increased. The spot-size variations are observed usin...
Any charged particle moving faster than light through a medium emits Cherenkov radiation. We show that charged particles moving faster than light through the vacuum emit Cherenkov radiation. How can a particle move faster than light? The weak speed of a charged particle can exceed the speed of light. By definition, the weak velocity ^v&w is ^C f inuvuC in&/^C f inuC in&, where v is the velocity...

How can a particle move faster than light? The weak speed of a charged particle can exceed the speed of light. By definition, the weak velocity v w is Ψ f in |v|Ψ in /Ψ f in |Ψ in , where v is the velocity ...
The setup of two different small scale teststands for measurements regarding an electron Cherenkov detector as part of the ILC polarimeters is presented. Component measurements already carried out are analyzed and others, foreseen for the near future, are discussed. The larger one of the two teststands features the old Cherenkov detector of the SLD experiment, which will be used as a reference ...
