Hypothetical low-mass particles, such as axions, provide a compelling explanation for the dark matter in the universe. Such particles are expected to emerge abundantly from the hot interior of stars. To test this prediction, the CERN Axion Solar Telescop
For reference, we point out that in theoretical physics that there is no consensus on the nature of the axion. At this stage, all that matters to us is that the mass of the axion is small. This fact corresponds to the statement: “In the theory modified within the framework of the Gra...
From this perspective, not only is the axion a common component that should emerge in any description of high energy physics, but it is also, in a sense, unavoidable. Indeed, many non-equivalent cycles should give rise to their own specific axions, leading to what is known as axion ...

A once-in-a-civilization burst of gamma rays set off an observing spree by more than 160 telescopes. It’s forcing scientists to revisit long-held theories—and it’s not done yet.

Planck-scale physics and solutions to the strongCPproblem without the axion We analyze the impact of quantum gravity on the possible solutions to the strong CP problem which utilize the spontaneously broken discrete symmetries, such as parity and time reversal invariance. We find that the stability...
The propagation ofγrays over very large distances provides new insights on the intergalactic medium and on fundamental physics. On their path to the Earth,γrays can annihilate with diffuse infrared or optical photons of the intergalactic medium, producinge+epairs. The density of these photons is...
