x-ray photon

An uncharged particle of energy, moving in waves produced by the interaction of high-speed electrons with a target (commonly tungsten). These particles vary from those of lower energy (1 to 0.1 A.U.), used in diagnostic imaging, to those of higher energy (0.1 to 10-4 A.U.), used in therapy. Synonym: roentgen ray

photon

a particle (quantum) of radiant energy.

x-ray photon
a particle of x-ray energy.

If an X-ray photon hits DNA, it typically cuts only a single DNA strand, a break that a cell can often repair.
In 60 of those TGFs, the energy of at least one gamma-ray photon exceeded 10 million electron-volts (MeV), about 300 times the energy of an X-ray photon in a typical medical scan.
The particle masses that could fill the role of dark matter would produce X-ray photons when they decay.
They detected X-ray photons on four separate occasions.
