DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QASTM/16/">B
 ootstrapping CFTs and QFTs</a>\nby Aninda Sinha (CHEP\, IISC\, Bengaluru) 
 as part of Quantum Aspects of Space-Time and Matter\n\n\nAbstract\nI will 
 review some recent developments in the bootstrap approach towards understa
 nding quantum field theories. I will begin by using the bootstrap to do ep
 silon expansion ala Wilson-Fisher to calculate critical exponents and OPE 
 coefficients (relevant for the 3d Ising model)—the latter being somethin
 g that is difficult to calculate using traditional Feynman diagram approac
 h. This is an example of a conformal field theory and will use techniques 
 of the conformal bootstrap. Then I will discuss some recent work to constr
 ain the space of S-matrices for pion scattering in the standard model of p
 article physics using the recent reincarnation of the S-matrix bootstrap. 
 In the course\, I will also introduce and examine certain quantum informat
 ion ideas which will aid us in understanding the space of S-matrices.\n
