Timelike Compton Scattering in Ultraperipheral Collisions
Exclusive photoproduction of dileptons, γN → ll N , is and will be measured in ultraperipheral collisions at hadron colliders. We demonstrate that the timelike deeply virtual Compton scattering (TCS) mechanism γq → llq, where the lepton pair comes from the subprocess γq → γ∗q, dominates in some accessible kinematical regions, thus opening a new way to study generalized parton distributions (GPD...
متن کاملTimelike Compton scattering: exclusive photoproduction of lepton pairs
We investigate the exclusive photoproduction of a heavy timelike photon which decays into a lepton pair, γp → `+`− p. This can be seen as the analog of deeply virtual Compton scattering, and we argue that the two processes are complementary for studying generalized parton distributions in the nucleon. In an unpolarized experiment the angular distribution of the leptons readily provides access t...
متن کاملStudy of the Compton scattering effect of soft tissue in PET imaging by Monte Carlo method
Introduction:In PET imaging, one or both of two annihilation photons may change the direction before reaching the detector due to Compton scattering interaction in body. .Methods:This article, a Monte Carlo simulation study, examined the effect of soft tissue on this error.In this work, the PET BiographTM 6 scanner, a simple geometry of soft tissue -including a sphere of soft tissue in center ...
متن کاملCompton Scattering
In the early 20th century, research into the interaction of X-rays with matter was an emerging field. It was observed that when a beam of X-rays is directed at an atom, an electron is ejected and the light is scattered through an angle θ, as illustrated below. Classical electromagnetism predicts that the wavelength of scattered rays should be equal to the initial wavelength; however, experiment...
متن کاملCompton scattering as a probe for materials investigation
This article investigates into the feasibility of using gamma radiation Compton backscatter spectra as a means of material characterization, with the view to developing a portable, hand held probe for investigative purposes such as searching for illicit substances hidden in wall or car door cavities.
