The Possible Signals from the D=6 Space-Time

Abstract

Based on the exceptional properties of U(1)_{em}-sterile neutrinos and their possible Majorana-Weyl space-time nature we continue to discuss our ideas about the existence in Standard Model some phenomena or hidden symmetries which are related to the extra global dimensions. We carry on discussing some open questions of the SM from the D=p_s+q_t=6 space-time geometry. The origin of the three families could be considered in analogue to the existing of two species- matter-antimatter in D=3+1 Minkowski space-time what can give the ternary relation for neutrinos masses. Apart from the possible existence of a "hidden neutrino boost" c_{new}> v_{neut} > c_{light} discussed in previous papers and a possible indication on v_{neut} > c_{light} first observed in OPERA2011 there could be some other signatures of a D=6-vacuum, for example, the possible signals of the breaking CPT-invariance and Q_{em}-conservation.
