Physics of Mirror Photons
The physics of kinetic mixing between ordinary and mirror photons is elucidated. An important role is played by four linear combinations we dub the physical photon, the sterile photon, the physical mirror photon, and the sterile mirror photon. Because of the mass degeneracy between the two gauge bosons, quantum coherence effects are important. The physical photon becomes a certain coherent supe...
متن کاملPhotons and Other Physics @ Dane
On overview of the main physics objectives of the Frascati-factory DAANE is presented. Study of CP violation in the K-meson system, Chiral Perturbation Theory tests in K-meson decays, low energy measurement of the hadronic cross-secton and the physics potential of gamma gamma interactions are discussed. A brief discussion of the hypernuclei and kaonic atom experiments is also included.
متن کاملNeutrons versus Photons in Solid State Physics
The comparaison between condensed matter studies using neutrons and photons is a well known subject which can be found in many text books. However the occurence of synchrotron source is strongly changing the situation. Some personal considerations about the possible future evolutions will be given.
متن کاملSingle and Entangled Photons
Quantum computing is a sought after technology that will greatly increase the speed and security of computations and communications. The understanding of quantum computing and information technology is dependent upon the understanding of quantum interactions. The difference between current computers and quantum computers lies in the fundamental units of information utilized. The qubit, which is...
متن کاملCDF Searches for New Physics with Photons
We present results of searches for new physics in final states with photons at CDF in approximately 1fb of pp̄ collisions at 1.96 TeV. We give an overview of the data-driven photon background estimation techniques used for the analyses. We report on a search for diphoton peaks and signature-based searches for γγ +X, lγ +X (X = e, μ, 6ET, γ) and tt̄γ. PACS. 13.85.Rm Limits on production of particl...
