Title:  Expansion of EYM Amplitudes in Gauge Invariant Vector Space 
Speaker: Dr.Xiaodi Li 
Coordinates: Room 613, 4pm, Thursday, October 29 

Abstract: Motivated by the problem of expanding single-trace tree-level amplitude of EYM theory to the BCJ basis of YM amplitudes, we present an alternative expansion formula in the gauge invariant vector space. To characterize this space, we compute its dimension and construct an explicit gauge invariant basis. Finally, We propose an algorithm to compute the expansion coefficients via differential operators.
