The names of supersymmetric partner particles of fermions are formed by s- + the name of the normal particle. E.g.:
- selectron sneutrino
- smuon neutrino
- stau sneutrino
(The names of superpartners of bosons are formed differently, by changing -on to -ino, e.g., gluino.)
I couldn't find any information online on how to pronounce these words. Would you pronounce "sfermion" (for instance) as /ˈɛs ˈfɝːmiɑn/ or /ˈsfɝːmiɑn/ or something else?
