“…Summing over the final spin states and averaging over the spin projections of the initial state leads to The procedure of integration in the rest frame of the decaying particle is discussed in equation (10.16) ff.of [12]. Furthermore, a mixed approach, where certain intermediate integrals are carried out covariantly, and only the final stages of the calculation are carried out in the rest frame of the decaying particle, is outlined in chap7.2.2 of [51]. In the actual evaluation, in the conventions of figure 4, we keep the outgoing neutrino momentum as our final integration variable and write the decay rate in the lab frame as follows (for the expression in the lab frame, see [52]),…”

We consider in detail the calculation of the decay rate of high-energy superluminal neutrinos against (charged) lepton pair Cerenkov radiation (LPCR), and neutrino pair Cerenkov radiation (NPCR), i.e., against the decay channels ν → ν e + e − and ν → ν ν ν. Under the hypothesis of a tachyonic nature of neutrinos, these decay channels put constraints on the lifetime of high-energy neutrinos for terrestrial experiments as well as on cosmic scales. For the oncoming neutrino, we use the Lorentz-covariant tachyonic relation Eν = p 2 − m 2 ν , where mν is the tachyonic mass parameter. We derive both threshold conditions as well as decay and energy loss rates, using the plane-wave fundamental bispinor solutions of the tachyonic Dirac equation. Various intricacies of rest frame versus lab frame calculations are highlighted. The results are compared to the observations of high-energy IceCube neutrinos of cosmological origin.

Abstract-This paper presents various applications where wide-band signals are the dominant factor. The approaches applied here are based on the present knowledge in the field of white light theory (the THz band), the particle theory of light, and the wave theory of light. White light theory is used to investigate wide-band applications of non-coherent electromagnetic waves in the GHz range represented by noise. In addition, the theoretical approaches to the field of white light are confirmed by various experiments with noise fields applied in the GHz range. These experiments show clear advantages of measurements performed by means of noise fields. The most important feature of these fields is the absence of interference effects.
