Photon Total Cross - sections
We discuss present predictions for the total γγ and γp cross-sections, highlighting why predictions differ. We present results from the Eikonal Minijet Model and improved predictions based on soft gluon resummation.
متن کاملMeasurement of Scattering and Absorption Cross Sections of Dyed Microspheres
Measurements of absorbance and fluorescence emission were carried out on aqueous suspensions of polystyrene (PS) microspheres with a diameter of 2.5 µm using a spectrophotometer with an integrating sphere detector. The apparatus and the principles of measurements were described in our earlier publications. Microspheres with and without green BODIPY(@) dye were measured. Placing the suspension i...
متن کاملAcoustical Absorption and Scattering Cross-sections of Spherical Bubble Clouds
The present work investigates the acoustical absorption and scattering cross-sections of spherical bubble clouds subject to harmonic far field pressure excitation. Bubble dynamics effects and energy dissipation due to viscosity, heat transfer, liquid compressibility and relative motion of the two phases are included. The equations of motion for the average flow and for the bubble radius are lin...
متن کاملTwo-photon absorption cross-sections of common photoinitiators
Recent interests in and applications of two-photon absorption (2PA) induced photopolymerization have afforded advanced opportunities to perform three-dimensionally resolved polymerization, resulting in intricate microfabrication and imaging. Many of the reported 2PA-induced polymerizations make use of commercially available photoinitiators, and a key parameter to consider is the two-photon abso...
متن کاملIsolated Prompt Photon Cross Sections
In ee and in hadron-hadron reactions at collider energies, prompt photons are observed and their cross sections are measured only if the photons are relatively isolated in phase space. Isolation is required to reduce various hadronic backgrounds including those from the electromagnetic decay of mesons, e.g., π → 2γ. The essence of isolation is that a cone of half-angle δ is drawn about the dire...
