It could be. When Steven Krivit was interviewing Rossi, he asked about some particular detail which would have meant that the Widom-Larson theory was on the right track. Rossi let it slip that it was more like proton capture going on. From that point on, Krivit was very antagonistic towards Rossi. It’s even on video somewhere.
In terms of theory, I’ll just wait & see, but I doubt Widom/Larson have it right. My bet would be on Y.E.Kim’s Bose-Einstein Condensate theory or K.P.Sinha’s theory.
It was more than that. Krivit caught Rossi cheating. Rossi also offered Krivit financial compensation which Krivit refused.
