Title: A CFT Dual for Celestial MHV Amplitudes Abstract: I will talk about a 2d CFT dual we constructed for 4d gluon MHV amplitudes in flat space, based on the papers 2403.18896 and 2312.07820. I will start with reviewing relevant basics of celestial holography, in particular, the challenges of understanding the role of translation invariance in the CFT dual. Then I will discuss the central object in my talk, leaf amplitudes, which are smooth functions that bridge usual (singular) flat space amplitudes and our simple CFT dual. I will then introduce the CFT dual, whose correlators reproduce gluon MHV amplitudes. It comprises two sectors, one with free fermions that give a current algebra, the other being Liouville theory. The key step is to show correlators of light operators in the semiclassical limit of Liouville theory are scalar contact Witten diagrams. (1:00 PM - 2:00 PM, 726 Broadway, 940, CCPP Seminar) | |||
