Quantamagazine on Juan Rojo’s charm-quark inside the proton

19 October 2022

The prestigious American science journal QuantaMagazine published an article on Nikhef researcher Juan Rojo’s new studies of the interior of the proton. Earlier this summer, he and an international team published a startling result: the proton occasionally contains charm quarks that are much heavier than the proton itself. This is possible thanks to the uncertainty of quantum mechanics. The article, with very nice graphics, can be read here (in English).
