A balloon debate at the FRPT 2022 conference pondered which particle offers most promise for clinical implementation of FLASH radiotherapy Debating particles Jean Bourhis, Billy Loo and John ...

Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn't as ...

A mystery concerning the structure of protons is a step closer to being solved. Two photons, not one, are exchanged in electron-proton interactions, a seven-year study indicates. A mystery concerning ...

During a deeply inelastic collision with a proton, a relativistic electron (highlighted in blue) can emit a high-energy photon (purple here) that penetrates interior of the proton, where it ‘sees’ ...

Collision course: diagram showing the real photon (γ) that is produced when an electron scatters from a proton. (Courtesy Nikos Sparveris/Temple University) New electron scattering data from the US ...

Nuclear physicists have used two different methods to measure the proton's electric form factor. But the deeper that they probe inside the proton, the more the results from these two different methods ...

A photon inside a proton can collide with a temporary complex of gluons, whose color charges (here shown in red, green and blue) can be collectively neutralized. Credit: IFJ PAN A photon inside a ...

Physicists have begun to explore the proton as if it were a subatomic planet. Cutaway maps display newfound details of the particle’s interior. The proton’s core features pressures more intense than ...

DENVER — The size of a proton, long thought to be well-understood, may remain a mystery for a while longer, according to physicists. Speaking Saturday at the April meeting of the American Physical ...

A mystery concerning the structure of protons is a step closer to being solved, thanks to a seven-year experiment led by researchers at MIT. For many years researchers have probed the structure of ...
