Everything on that fine man's diagram is matter, including the squiggly lines marked with lower-case Greek gamma letters, asterisks notwithstanding.
Some are photons, which are massless, but, since all photons travel, without exception, at the speed of light in a vacuum (speed varies, of course, in other substances with the frequency/wavelength), all photons have energy.
