SUMMARY:Conformal Bootstrap in the Lightcone Limit
DESCRIPTION:Featuring Daliang Li\, Johns Hopkins\n\nPart of the HET Seminar
	 Series.\n\nAbstract: In this talk\, we will explore the structures of conf
	ormal field theories (CFTs) that emerge from the conformal bootstrap in the
	 lightcone limit. We start by analyzing a 4-point function of real scalars\
	, showing the existence of large spin\, double-twist operators in unitary C
	FTs in d>2. These operators correspond to two-particle bound states in AdS 
	and their anomalous dimensions correspond to the binding energies between t
	he two particles. I will demonstrate the features of the binding energies a
	rising from gauge and gravitational interactions. Then\, using the 4-point 
	function involving conserved currents and the stress energy tensor\, I will
	 establish a relation between the energy flux positivity in CFT and the att
	ractiveness of gravity at large distances in AdS. Finally\, I will use the 
	bootstrap machinery to prove the conformal collider bounds for all unitarit
	y CFTs in d>2.
