SUMMARY:Where is all the antimatter?\, NPAC (Nuclear/Particle/Astro/Co
 smo) Forum\, Nuno Barros\, University of Pennsylvania
DESCRIPTION:Everything we know about the microscopic world tells us th
 at the universe should be composed of equal parts matter and antimatte
 r. All known particle interactions and decays always produce equal amo
 unt of each.<br>
\nYet all the known\, observable\, universe is compos
 ed solely of matter\, suggesting that a small surplus of matter might 
 have taken form shortly after the Big Bang.<br>
\nA possible explanati
 on for this asymmetry may be that neutrinos\, unlike all other fundame
 ntal particles of Nature\, may have behavior that distinguishes matter
  and antimatter. Ironically\, the property that allows this is that ne
 utrinos<br>
\nand antineutrinos may be the same thing.  Many experimen
 ts worldwide that are running or under construction\, are investigatin
 g this possibility.<br>
\nThis talk will discuss this problem and the 
 different approaches to address it in both present and  upcoming neutr
 ino<br>
\nexperiments\, with particular emphasis on long baseline neut
 rino oscillations with DUNE and neutrinoless double beta  decay with S
 NO+. The physics goals and expectations of these experiments will also
  be discussed.
