directions. The angle $\theta $, measured from the direction of their initial momenta, is the same but the total angles are different, correspondingly. The averaging procedure would shift the maxima and give rise to more smooth distribution. Nevertheless, some indications on the substructure with maxima at definite angles have been found at the same energies by CERES collaboration [@26]. It is not clear yet if it can be ascribed to Cherenkov gluons. To recover a definite maximum, it would be better to detect a single parton jet, i.e. to have a trigger.

The prediction of asymmetrical in-medium widening of [**any**]{} resonance at its low-mass side due to Cherenkov gluons is universal. This universality is definitely supported by experiment. Very clear signals of the excess on the low-mass sides of $\rho $, $\omega$ and $\phi$ mesons have been seen in KEK [@5; @Muto]. This effect for $\omega $-meson is also studied by CBELSA/TAPS-collaborartion [@7a]. Slight asymmetry of $\phi $-meson near 0.9 - 1 GeV is noticeable in the Fig. 2 shown above but the error bars are large there. We did not try to fit it just to deal with as small number of parameters as possible. There are some indications
