The Tree Formula for MHV Graviton Amplitudes (2009)
Nguyen, Dung, Spradlin, Marcus, Volovich, Anastasia, Wen, Congkao
We present and prove a formula for the MHV scattering amplitude of n gravitons at tree level. Some of the more interesting features of the formula, which set it apart as being significantly different...
Correlation Functions in Non-Relativistic Holography (2009)
Volovich, Anastasia, Wen, Congkao
Recently constructed gravity solutions with Schrodinger symmetry provide a new example of AdS/CFT-type dualities for the type of non-relativistic field theories relevant to certain cold atom systems....
Three Applications of a Bonus Relation for Gravity Amplitudes (2008)
Spradlin, Marcus, Volovich, Anastasia, Wen, Congkao
Arkani-Hamed et. al. have recently shown that all tree-level scattering amplitudes in maximal supergravity exhibit exceptionally soft behavior when two supermomenta are taken to infinity in a...
Three-Loop Leading Singularities and BDS Ansatz for Five Particles (2008)
Spradlin, Marcus, Volovich, Anastasia, Wen, Congkao
We use the leading singularity technique to determine the planar three-loop five-particle amplitude in N=4 super Yang-Mills in terms of a simple basis of integrals. We analytically compute the...
Compact Formulas for Tree Amplitudes of Six Partons (2005)
Compact results are obtained for tree-level non-MHV amplitudes of six fermions and of four fermions and two gluons, by using extended BCF/BCFW rules. Combining with previous results, complete set of...
Recursion Relations for Tree Amplitudes in Super Gauge Theories (2005)
Using newly proposed BCF/BCFW recursion relations, compact formulas are obtained for tree-level n-gluon amplitudes of helicity structure --++...+. We then make an extension of these recursion...
Systematics of One-Loop Scattering Amplitudes in N=4 Super Yang-Mills Theories (2004)
One-loop scattering amplitudes in N=4 super Yang-Mills (SYM) theories are analyzed in the paradigm of maximal helicity violating Feynman diagrams. There are very limited number of loop integrals to...
One-Loop Maximal Helicity Violating Amplitudes in N=4 Super Yang-Mills Theories (2004)
One-loop maximal helicity violating (MHV) amplitudes in N=4 super Yang-Mills (SYM) theories are analyzed, using the prescription of Cachazo, Svrcek, and Witten (CSW). The relations between leading...
