DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LIJC/23/">An
  Operator Product Expansion for Form Factors</a>\nby Matthias Wilhelm (Nie
 ls Bohr Institutet) as part of London Integrability Journal Club\n\n\nAbst
 ract\nIn this talk\, I discuss an operator product expansion for planar fo
 rm factors of local operators in N=4 SYM theory. In this expansion\, a for
 m factor is decomposed into a sequence of known pentagon transitions and a
  new universal object - the form factor transition. This transition is sub
 ject to a set of non-trivial bootstrap constraints\, which can be used to 
 determine it at finite coupling. I demonstrate this for MHV form factors o
 f the chiral half of the stress tensor supermultiplet\, which in particula
 r contains the chiral Lagrangian and the 20'.\n
