DESCRIPTION:Speakers: Chandan Hati (Technische Universität München)\nAn 
 observation of Neutron-antineutron ($n-\\bar{n}$) oscillations\, would dir
 ectly imply physics beyond the Standard Model violating baryon number by t
 wo units $|\\Delta B| = 2$ and hence might provide a close link to the mec
 hanism behind the observed baryon asymmetry of the Universe. In this talk\
 , I will discuss the consequences of such a discovery in the near future\,
  e.g. at the Deep Underground Neutrino Experiment or the European Spallati
 on Source\, for baryogenesis mechanisms. I will discuss both an effective 
 field theory approach and a more concrete simplified model approach with a
  source of CP violation and different hierarchies between the scales of ne
 w physics. I will also highlight the complementarity of $n-\\bar{n}$~oscil
 lation searches with other experimental constraints from dinucleon decay\,
  LHC\, and meson oscillations and discuss how an observation of $n-\\bar{n
 }$~oscillation can rule out many potential baryogenesis scenarios and favo
 ur only a select few providing an exciting possibility to understand our m
 atter dominated Universe at laboratory.\n\nhttps://indico.ific.uv.es/event
