 lloquium/1/">Machine Learning for Particle Theory</a>\nby Tilman Plehn (He
 idelberg University\, Germany) as part of IISc CHEP colloquium\n\n\nAbstra
 ct\nLHC physics is a unique field in the sense that we compare vast and hi
 ghly complex data sets with precise first-principle predictions. I will st
 art with a few examples\, where machine learning offers unique opportuniti
 es all over LHC physics. With a focus on particle theory\, I will show how
  generative neural networks can supplement standard simulation methods and
  discuss their conceptional advantages. I will then explain how generative
  adversarial and flow-based networks can invert detector simulations or QC
 D parton showers in a\nmathematically consistent manner. Finally\, I will 
 illustrate how the same networks can infer the structure of QCD splittings
  forming jets.\n

 lloquium/2/">Effective Field Theories and Positivity Bounds</a>\nby Andrew
  Tolley (Imperial College London) as part of IISc CHEP colloquium\n\n\nAbs
 tract\nEffective field theories are the central tool of modern physics\, u
 tilized in gravity\, cosmology\, particle physics and condensed matter. EF
 Ts providing a framework in which low energy physics can be described larg
 ely independently of the high energy completion\, which is one of the reas
 ons they are so powerful. Despite this there has been a recent recognition
  that high energy physics does limit the range of possible low energy effe
 ctive theories. The sharpest of these restrictions are the constraints tha
 t emerge from Lorentz invariance\, locality and unitarity in the form of `
 positivity bounds'. I will review some recent progress related to the appl
 ication of positivity bounds to EFTs\, and discuss implications for gravit
 ational effective field theories\, interacting massive spin theories\, and
  theories with soft scattering behaviour such as Galileons.\n
