If a particle propagates in a material with a velocity larger than the speed of light in this material, Cherenkov radiation is emitted at a characteristic angle that depends on the particle velocity and the refractive index of the material. Transition Radiation: If a charged particle is crossing the ...

conceptual design of a polarized medium energy electron
... The design has now finally evolved into a ring-ring collider in which the colliding electron beam will also be stored in a ring while CEBAF will only be used as a fullenergy injector [4], thus requiring no further upgrade beyond 12 GeV. The ring-ring scenario does not suffer any disadvantage in reac ...

From Quantum Mechanics to String Theory
... forces are mediated by the exchange of virtual particles, which carry energy and momentum inconsistent with their masses using quantum uncertainty. This leads to a decrease of force strength with distance, and in the case of massive mediators, an effective range for the force particle interactions a ...
