Fig.1: Schematic description of the Cerenkov Radiation

In 1888 the great Oliver Heaviside first predicted theoretically a conical radiation when a point charge (an electron) moves uniformly and rectilinearly both in the ether and in a nondispersive medium with a speed higher than the speed of light in this medium.

P.A. Cerenkov (1934-1937) studied the light in many transparent media irradiated with radiation from uranium. Only the exhaustive experiments of P.A. Cerenkov characterized completely this new kind of radiation. A complete theory of the Cerenkov radiation was developed by I.E. Tamm and I.M. Frank in 1937.

In 1971, in his Doctoral Thesis [9], D. B. Ion developed a general classical and quantum theory of the mesonic erenkov-like radiation in hadronic media [see D. B. Ion, Mesonic erenkov-like Effect as Possible Mechanism of Meson Production in Hadronic Interactions, DSc Thesis, Bucharest University, 1971]. Predicted completely all the properties of the pionic erenkov-like radiation in the case when the pionic refractive index is given by a single pole approximation. Obtained a good agreement with the integrated cross section of the single meson production in the hadronic collisions (see D. B. Ion and F. Nichitiu, Nucl. Phys. B 29 (1971) 547-556).

From energy-momentum conservation laws: E1=+E2, p1=k+p2, we obtainSR-angle theta(1k):

SR-angle theta(12) and theta(2k):

An experimental test of the SR can be obtained using RICH detectors. For this accurate measurements of the SR-ring radius are needed As is well known, in an usual RICH detector a spherical mirror focuses all photons emitted at a erenkov angle along the particle trajectory at the same radius on the focal plane. Photon sensitive detectors placed at the focal plane detect the resulting ring image. Then, a fundamental test of SR can be based on SR-prediction on ring radii:Fig.6Radiator

Observed 7 anomalous rings with unusual properties which, apparently, are produced by tahions [see: S. Vodopianov et al., Nucl. Instr. Meth. B 201, 266 (2003) A.S. Vodopianov, V.P. Zrelov and A.A.
