NPAC (Nuclear/Particle/Astro/Cosmo) Forum
Tests of Lorentz Invariance with Neutrinos
Time: 11:00 am
Place: 5280 Chamberlin Hall
Speaker: Teppei Katori, MIT
Abstract: Lorentz violation is a predicted signal from Planck scale physics. Since neutrino oscillation experiments are natural interferometers, they may be sensitive to small space-time effect, such as Lorentz violation through their sidereal time dependence. The sensitivity is comparable to precision optical measurements (10E-19 GeV). Thus, neutrino oscillations may be the first place where we see Lorentz and CPT violation.<br>
Recently the MiniBooNE neutrino oscillation experiment published electron and anti-electron neutrino appearance oscillation results that cannot be understood within the accepted three-massive-neutrinos oscillation model. In this talk, I will introduce Lorentz violation and Lorentz violating neutrino oscillations. Then, I examine whether the MiniBooNE data may be explained through a Lorentz violation model. Finally, I discuss how these results and other Lorentz violation tests address the &quot;superluminal neutrino observation&quot; from OPERA experiment.<br>
