SUMMARY: Twistors and Amplitudes - Andrew Hodges - Oxford

CONTACT:Mike Blake
DESCRIPTION:Twistor geometry has been studied for 50 years\, but has much 
 more recently taken a central place in the theory of scattering amplitudes
  for fundamental particles.  I will review the main features of twistor re
 presentation\, as first elucidated by Roger Penrose\, and explain their re
 lationship to modern developments such as the 'amplituhedron' of Nima Arka
 ni-Hamed et al.  The talk will be similar in character to the recent revie
 w Twistors and amplitudes\, Phil. Trans. R. Soc. A 373: 20140248.
