DESCRIPTION:Andrea Guerrieri (Perimeter Institute and University of Pad
 ova)\nDimension six operators in the SM are of central importance in the q
 uest for new physics at the LHC. Unfortunately\, the associated Wilson coe
 fficients are notoriously difficult to bound using the standard positivity
  arguments.\nIn this talk\, using a simplified model\, I will argue how we
  might have a chance to determine sharp bounds on such coefficients.\nI wi
 ll discuss the introduction of the EFT cutoff within the Bootstrap constra
 ints\, and how to carve out the EFT region.\nI will introduce the concept 
 of Low Spin and UV Dominance\, and how their measurement can give a quick 
 picture of the physics at the boundary of the allowed space.\nFinally\, I 
 will comment on the EFT cutoff dependence and how to use it to build a bri
 dge between the bootstrap and the positivity bounds.
