Neutrinos may not be neutral after all!
Do neutrinos affect radioactive decay? That's what new research at Purdue seems to suggest. When researchers at Purdue were looking for a reliable way to generate random numbers, they thought they were smart to use radioactive decay - after all the rate of decay was a known constant (for a given material) but the decay of any particular atom was truly random. But what they discovered may have huge implications for the Standard Model, for physics and for cosmology.
As the researchers pored through published data on specific isotopes, they found disagreement in the measured decay rates – odd for supposed physical constants. Checking data collected at Brookhaven National Laboratory on Long Island and the Federal Physical and Technical Institute in Germany, they came across something even more surprising: long-term observation of the decay rate of silicon-32 and radium-226 seemed to show a small seasonal variation. The decay rate was ever so slightly faster in winter than in summer.In addition, during a solar flare event in Dec 2006, a Purdue researcher, observing day in manganese-54, noticed that the decay rate began to drop almost 36 hours before the flare event
