Photon-photon Collisions - 9th International Workshop On Photon-photon Collisions
Author: D O Caldwell
Publisher: World Scientific
ISBN: 981455460X
Category :
Languages : en
Pages : 532
Book Description
The proceedings blend current and future two-photon physics. Developments since the last Photon-Photon Workshop four years ago are summarized, and the future of the field is projected, not only at existing accelerators, but also at heavy-ion colliders B-factories, and especially linear colliders with back-scattered laser beams.

Two-photon Physics: From DaΦne To Lep200 And Beyond

ISBN: 981455040X

Languages : en
Pages : 358
Book Description
Two-photon physics, i.e. photon-photon collisions in electron-positron colliders, a relatively new field in elementary particle physics, has become very popular in the last 20 years. Many experiments have been performed in this field, and the theoretical implications (in particular in quantum chromodynamics) have been studied in much detail. Nine international workshops devoted to two-photon physics have taken place between 1973 and 1992.This meeting was particularly timely, since a new generation of electron-positron colliders is presently being built or planned. These colliders will involve a large spectrum of beam energies, but their common characteristics should be a high particle flux (luminosity). This should allow for measuring many new phenomena as well as for studying known processes with much higher precision than before. Particularly promising is the prospect of building a dedicated high-energy photon collider; this should become possible using a laser technique allowing for the “conversion” of a linear electron beam into a photon beam.Over 60 physicists (both experimentalists and theorists), mainly from European countries (France, Britain, Italy, Germany, Russia, as well as Sweden and Switzerland), discussed these new possibilities at the above meeting. Over 30 talks were presented and many extended debates took place.

Production of Photons in Relativistic Heavy-ion Collisions
Author:

ISBN:
Category :
Languages : en
Pages :
Book Description
In this work it is shown that the use of a hydrodynamical model of heavy-ion collisions which incorporates recent developments, together with updated photon emission rates, greatly improves agreement with both ALICE and PHENIX measurements of direct photons, supporting the idea that thermal photons are the dominant source of direct photon momentum anisotropy. The event-by-event hydrodynamical model uses the impact parameter dependent Glasma model (IP-Glasma) initial states and includes, for the first time, both shear and bulk viscosities, along with second-order couplings between the two viscosities. Furthermore, the effect of both shear and bulk viscosities on the photon rates is studied, and those transport coefficients are shown to have measurable consequences on the photon momentum anisotropy.

Two-photon Physics in Nucleus-nucleus Collisions at RHIC.
Author:
Publisher:
ISBN:
Category :
Languages : en
Pages : 17
Book Description
Ultra-relativistic heavy-ions carry strong electromagnetic and nuclear fields. Interactions between these fields in peripheral nucleus-nucleus collisions can probe many interesting physics topics. This presentation will focus on coherent two-photon and photonuclear processes at RHIC. The rates for these interactions will be high. The coherent coupling of all the protons in the nucleus enhances the equivalent photon flux by a factor Z2 up to an energy of (almost equal to) 3 GeV. The plans for studying coherent interactions with the STAR experiment will be discussed. Experimental techniques for separating signal from background will be presented.
