Generation of hyperentangled photon pairs.
We experimentally demonstrate the first quantum system entangled in every degree of freedom (hyperentangled). Using pairs of photons produced in spontaneous parametric down-conversion, we verify entanglement by observing a Bell-type inequality violation in each degree of freedom: polarization, spatial mode, and time energy. We also produce and characterize maximally hyperentangled states and no...
متن کاملExperimental Status of Photon Photon into Baryon Antibaryon Pairs
The exclusive production of BB pairs in the collisions of two quasi-real photons have been studied in different experiments at e+e− colliders. Results are presented for the processes γ γ → pp and γ γ → . The cross-section measurements are compared with the recent analytic calculations based on the quark-diquark model predictions. Monte Carlo studies have been done to investigate the PEP-N expec...
متن کاملMeasuring spatial correlations of photon pairs by automated raster scanning with spatial light modulators
We demonstrate the use of a phase-only spatial light modulator for the measurement of transverse spatial distributions of coincidence counts between twin photon beams, in a fully automated fashion. This is accomplished by means of the polarization dependence of the modulator, which allows the conversion of a phase pattern into an amplitude pattern. We also present a correction procedure, that a...
متن کاملDetecting a light Higgs boson at the Fermilab Tevatron through enhanced decays to photon pairs
We analyze the prospects of the Tevatron for finding a Higgs boson in the two photon decay mode. We conclude that the Standard Model (SM) Higgs boson will likely not be discovered in this mode. However, we motivate several theories beyond the SM, including the MSSM, that predict a Higgs boson with enhanced branching fractions into photons, and calculate the luminosity needed to discover a gener...
متن کاملTwo-Photon Annihilation into Baryon-Antibaryon Pairs
We study the handbag contribution to two-photon annihilation into baryon-antibaryon pairs at large energy and momentum transfer. We derive factorization of the process amplitude into a hard γγ → qq subprocess and form factors describing the soft qq → BB transition, assuming that the process is dominated by configurations where the (anti)quark approximately carries the full momentum of the (anti...
