This will be very interesting when this array is fully up and running as it can either confirm or refute aspects of the Standard Model as they pertain to neutrino behavior.David Schroederhttps://www.blogger.com/profile/18048116250413347228noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-20686653624584243802008-05-31T09:31:00.000-04:002008-05-31T09:31:00.000-04:00Hi Bee,If the question is how long the oscillation...Hi Bee,<BR/><BR/>If the question is how long the oscillation period would be in a different rest-frame that is just a Lorentz-transformation. I.e. yes, we would think for the neutrino time runs slower. Slow moving neutrinos are allowed by theory, but 'slow' in itself is not meaningful, it is always only 'slow relative to'.<BR/><BR/>Thanks for taking the time to answer and yes the question was Phil Warnellhttps://www.blogger.com/profile/15671311338712852659noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-40713541338620820872008-05-31T08:46:00.000-04:002008-05-31T08:46:00.000-04:00Hi Phil,I'm not entirely sure I understand the que...Hi Phil,<BR/><BR/>I'm not entirely sure I understand the question. Neutrino oscillation isn't an effect of one neutrino with a mass. It is an effect of a neutrino that is produced in a flavor eigenstate which is *not* a mass (energy) eigenstate and subsequently mixes different flavors. If you start with a mass eigenstate (in whatever restframe) it will remain a mass-eigenstate and not mix. <BR/>Sabine Hossenfelderhttps://www.blogger.com/profile/06151209308084588985noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-80568076412523961392008-05-31T07:49:00.000-04:002008-05-31T07:49:00.000-04:00Hi Bee,With your current post drawing my attention...Hi Bee,<BR/><BR/>With your current post drawing my attention to this one, which you wrote some time back, I would first like to say it is certainly an excellent synopsis. Subsequently, it also has arisen in me a question, which I hope you will be kind enough to answer?
