Recent Advances in Scattering Amplitudes


we have been made aware of a very convincing phone scam that is focusing on our workshop participants. Participants may be contacted by phone by a firm called Business Travel Management to arrange accommodation for workshops and/or programmes.  This includes a request to enter credit card information.

Please note, INI will never contact you over the phone requesting card details. We take all payments via the University of Cambridge Online store

If you have been contacted by this company please contact us as soon as possible.

2nd April 2012 to 4th April 2012

Workshop Theme

Over the past years, major progress has been made in understanding the perturbative regime of Yang-Mills theory and gravity. This progress was initially prompted by Witten's discovery in December 2003 that tree-level scattering amplitudes of gluons in gauge theory can equivalently be computed by using a topological string theory with a supersymmetric version of Penrose's twistor space as its target space.

Since then, impressive new results in the calculation of quantum scattering amplitudes in gauge theory and gravity have been obtained thanks to new twistor-string inspired methods. This progress has also been made possible because of the fruitful exchange of ideas between three previously disconnected communities of researchers: string theorists, phenomenologists and mathematicians with interests in Penrose's twistor theory. The subject continues to expand rapidly, with new approaches and connections appearing at a dramatic pace including holography, Wilson loops, integrability, Grassmannians and momentum twistors.

The purpose of the mini-workshop will be to provide the opportunity for researchers working in this wide-ranging and rapidly evolving area to meet. The scientific goals of the workshop will be to review recent progress, stimulate interaction and collaboration among participants, and inspire further outstanding developments in the field.
