Title
The Proton size puzzle reinforced! An international team of scientists confirms a surprisingly small proton radius with laser spectroscopy of exotic hydrogen.
This article discusses a research paper on the measurement of the electric charge radius of the proton, which is an extended object made of three quarks bound by gluons. It references a study published in an issue of "Science." It tackles the use of laser spectroscopy of muonic hydrogen and research efforts to explain the proton discrepancy.
