SUMMARY:A panoramic view of infrared singularities - Chris White\, Glasgow
DTSTART:20160114T130000Z

UID:TALK62808@talks.cam.ac.uk
CONTACT:Dr. Piotr Tourkine
DESCRIPTION:The study of infrared singularities\, due to the emission of 
 “soft” (low momentum) gauge bosons\, remains a highly active research 
 area in a variety of quantum field theories. After motivating both phenome
 nological and formal reasons as to why we should care about IR singulariti
 es\, this talk will review their structure in QED\, QCD and quantum gravit
 y\, examining the similarities and differences between these three context
 s. The role of Wilson lines will be examined\, which provide a useful unif
 ying language. Finally\, I will examine recent work on moving beyond the s
 oft approximation\, and why this might be useful.
