Three mistakes in the article:" The OPERA neutrino velocity result and the synchronisation of clocks"
O.Besida
We have found three mistakes in the article \" The OPERA neutrino velocity result and the synchronisation of clocks, arXiV:1109.6160\" by Contaldi \\cite{Contaldi}. First, the angular definition of the latitude in the geoid definition leads to a prolate spheroid (rugby balloon shape) instead of an oblate spheroid with an equatorial flattening as usual. Second, Contaldi forgot a cosine of the latitude in the centripetal contribution term. And last but not least, a deep conceptual mistake was done believing that an atomic clock or any timekeeper apparatus was carried in a journey by car or plane between CERN to Gran Sasso; instead of that atomic clocks are continuously resynchronized through a GPS device, and this variation of potential term applies only for the neutrino travel itself. Thus instead of a $\\Delta t \\approx 30ns $ correction claimed by Contaldi in a travel of 12 hours plus 4 days at rest for an atomic clock, we have found a time correction only for the neutrino itself $\\Delta t=3.88 \\, 10^{-16} s$! That means, that this paper (arXiv:1109.6160) \\cite{Contaldi} does not give the right explanation why the neutrino travel faster than the speed of light in the CERN-OPERA neutrino experiment.
