Do antineutrinos contribute to Cherenkov radiation?

I think that there needs to be a charged light speed particle to make Cherenkov radiation, so neutrinos of any kind are out.

The lepton number “charge” isn’t the same as ‘real’ charge, at least for the purposes of making Cherenkov radiation.
However, an antineutrino collision with an electron would/could cause Cherenkov radiation.
(Which is how to find neutrinos anyways.) -

Can you expand on this or provide an article?

Based on the above? How so?

Ok found something interesting:
https://en.wikipedia.org/wiki/Glashow_resonance
In 1959, the theoretical physicist Sheldon Glashow used the standard model of particle physics to predict1 that negatively charged W bosons (W− bosons) can be formed in the collisions between an electron and an electron antineutrino (the antimatter version of an electron neutrino). This process is now called the Glashow resonance, and occurs for electron antineutrinos that have energies of about 6.3 petaelectronvolts (1 PeV is 1015 eV).

When a neutrino interacts with matter, charged particles are produced. These emit light known as Cherenkov radiation when they travel through a transparent medium (such as ice or water) at a speed greater than the speed of light in that medium.

Antineutrinos that interact with matter through the Glashow resonance are expected to produce characteristic events in which the resulting W− boson decays into a cascade of secondary particles, including particles called hadrons. Roughly 5% of the neutrino energy in these events is expected to be taken up by secondary particles that are neutral or don’t have enough energy to produce Cherenkov radiation5, limiting the amount of energy that can be observed to about 6.0 PeV. Moreover, low-energy muons are expected to be produced in the cascade, and to outrun the wavefront of the Cherenkov radiation at a high enough rate to trigger early pulses of light that would be detected by the DOMs.

I suspect this phenomenon is stronger with antineutrinos in nuclear reactors rather than neutrinos, since its fission with production of W-bosons.
-
The two W bosons are verified mediators of neutrino absorption and emission. During these processes, the W± boson charge induces electron or positron emission or absorption, thus causing nuclear transmutation.
Someone on Wiki added this for the W-boson entry, wonder what that means?
