In 1971, in his Doctoral Thesis [9], D. B. Ion developed a general classical and quantum theory of the mesonic Čerenkov-like radiation in hadronic media [see D. B. Ion, Mesonic erenkov-like radiation in hadronic media [ Čerenkov-like Effect as Possible Mechanism of Meson Production in Hadronic Interactions, DSc Thesis, Bucharest University, 1971]. Interactions Predicted completely all the properties of the pionic Čerenkov-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: E 1=ω+E 2, p 1=k+p 2, we obtain • SČR-angle theta(1 k): • SČR-angle theta(12) and theta(2 k):

1. An experimental test of the SČR can be obtained using RICH detectors. For this accurate measurements of the SČR-ring radius are needed 2. As is well known, in an usual RICH detector a spherical mirror focuses all photons emitted at a Čerenkov 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. 3. Then, a fundamental test of SČR can be based on SČR-prediction on ring radii: Radiator Fig. 6

A. S. Vodopianov, V. P. Zrelov, and A. A. Tyapkin [14]. They studied the anomalous Cherenkov radiation obtained in the relativistic lead ion beam at SPSCERN. 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.
