This particle's "spin crisis" is still unresolved. Even though it accidentally helped discover neutrinos, the Super-Kamiokande detector was initially intended to study a phenomenon involving this particle.
This particle's "spin crisis" is still unresolved. Even though it accidentally helped discover neutrinos, the Super-Kamiokande detector was initially intended to study a phenomenon involving this particle. These specific particles' interactions with the CMBR lead to the GZK cutoff. Many GUTs put this particle's halflife when free at about 10 to the 36th years, though its decay has never been observed. This baryon is composed of two up quarks and a down quark, and it is the most common constituent of a cosmic ray. A positron orbits this particle's anti-particle in antihydrogen. For 10 points, identify this positively charged particle found alongside neutrons in atomic nuclei.
