DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LIJC/41/">OP
 E coefficients in ABJM theory with giants</a>\nby Yunfeng Jiang (Southeast
  U.\, Nanjing) as part of London Integrability Journal Club\n\n\nAbstract\
 nIn this talk\, I will discuss a family of three-point functions in ABJM t
 heory\, both at weak and strong coupling. This family of three-point funct
 ions involve two BPS sub-determinant operators called giant gravitons and 
 one single trace operator\, which can be BPS or non-BPS. In the first part
  of the talk\, I will explain how to compute this type of three-point func
 tion at weak coupling using a large N effective field theory. The structur
 e constant is given by the overlap of an integrable matrix product state a
 nd a Bethe state. In the second part\, I will first clarify the prescripti
 on of computation at strong coupling. I will show that it is important to 
 perform an average over the moduli space and also take into account the co
 ntributions from wave functions. The prescription is tested in N=4 SYM the
 ory and then applied to ABJM theory.\n
