DESCRIPTION:Speakers: Paolo Crivelli (ETH Zurich (CH))\n\nAbstract:\nFollo
 wing the overview of the physics motivation for feebly interacting particl
 es (FIPs)\, this lecture will review the experimental programme dedicated 
 to their search at CERN's Super Proton Synchrotron (SPS). Over the past fo
 ur decades\, the SPS has played a pioneering role in the exploration of hi
 dden sectors\, evolving from early beam-dump experiments to today's state-
 of-the-art fixed-target facilities exploring physics beyond the Standard M
 odel at the intensity frontier.\nThe lecture will present the complementar
 y experimental techniques employed at the SPS\, including missing-energy a
 nd missing-momentum searches for invisible particles\, as well as searches
  for visible decays of long-lived particles. It will discuss how these app
 roaches provide sensitivity to a broad range of theoretical scenarios whil
 e highlighting their complementarity and recent experimental progress.\nPa
 rticular emphasis will be placed on the unique capabilities of the SPS\, w
 hose versatile beam infrastructure supports a diverse programme probing da
 rk photons\, light dark matter\, axion-like particles\, heavy neutral lept
 ons\, and other feebly interacting particles over a wide range of masses a
 nd couplings. The lecture will conclude with an outlook on future opportun
 ities for FIP searches at the CERN SPS.\nBio: \nPaolo Crivelli is Profess
 or of Experimental Particle Physics at ETH Zurich. His research focuses on
  precision tests of fundamental symmetries and the search for physics beyo
 nd the Standard Model using exotic atoms\, antimatter systems\, and high-i
 ntensity fixed-target experiments.\nHe is co-spokesperson of the NA64 expe
 riment at CERN\, which pioneered the missing-energy and missing-momentum t
 echniques using the active beam-dump approach to search for feebly interac
 ting particles and light dark matter at the SPS. His current research also
  includes the development of future intensity-frontier experiments and pre
 cision measurements probing new physics.\n\nhttps://indico.cern.ch/event/1
