SUMMARY:Neutrinos: A window into the unknown\, Physics Department Coll
 oquium\, Justin Evans\, University of Manchester
DESCRIPTION:Whilst the Standard Model of Particle Physics has been spe
 ctacularly successful\, it leaves some of the most profound questions 
 unanswered. Why does the Universe contain more matter than antimatter?
  What is the nature of dark matter? How do the forces of nature unify?
 
\n
\nNeutrinos offer a uniquely powerful probe of new physics. Their 
 ability to oscillate between flavours is already clear evidence of phy
 sics beyond the Standard Model. But the mechanism behind the neutrinoâ
 €™s tiny mass remains unknown\, making the neutrino sector one of the 
 most promising frontiers for discovery.
\n
\nI will explore how we use
  neutrinos as probes of the unknown\, with a particular focus on the s
 earch for sterile neutrinos: hypothetical new states that do not inter
 act via the Standard Model forces. I will highlight how advances in de
 tector technology\, especially liquid-argon time projection chambers\,
  have transformed our ability to image neutrino interactions with unpr
 ecedented precision.
\n
\nDrawing on results from the MicroBooNE exper
 iment\, the first large-scale liquid-argon detector in the United Stat
 es\, I will show how we are resolving long-standing anomalies and open
 ing new windows into hidden sectors. I will then look ahead to the Dee
 p Underground Neutrino Experiment (DUNE)\, a next-generation facility 
 spanning 1\,300 km from Fermilab to South Dakota\, which will be the w
 orld’s most comprehensive facility for understanding neutrinos and u
 sing them to reveal the physics shaping our Universe.
