▁an ▁ax ion ), ▁there ▁is ▁a ▁ferm ion ▁super part ner ▁as ▁well ▁as ▁a ▁second , ▁real ▁scalar ▁field . ▁ ▁For ▁ax ions , ▁these ▁particles ▁are ▁often ▁referred ▁to ▁as ▁ax inos ▁and ▁sa x ions . ▁ ▁In ▁extended ▁su pers ym met ry ▁there ▁may ▁be ▁more ▁than ▁one ▁super part icle ▁for ▁a ▁given ▁particle . ▁For ▁instance , ▁with ▁two ▁copies ▁of ▁su pers ym met ry ▁in ▁four ▁dimensions , ▁a ▁phot on ▁would ▁have ▁two ▁ferm ion ▁super part ners ▁and ▁a ▁scalar ▁super part ner . ▁ ▁In ▁zero ▁dimensions ▁it ▁is ▁possible ▁to ▁have ▁su pers ym met ry , ▁but ▁no ▁super part ners . ▁However , ▁this ▁is ▁the ▁only ▁situation ▁where ▁su pers ym met ry ▁does ▁not ▁imply ▁the ▁existence ▁of ▁super part ners . ▁ ▁Rec re ating ▁super part ners ▁ ▁If ▁the ▁su pers ym met ry ▁theory ▁is ▁correct , ▁it ▁should ▁be ▁possible ▁to ▁re create ▁these ▁particles ▁in ▁high - energy ▁particle ▁acceler ators . ▁Do ing ▁so ▁will ▁not ▁be ▁an ▁easy ▁task ; ▁these ▁particles ▁may ▁have ▁masses ▁up ▁to ▁a ▁thousand ▁times ▁greater ▁than ▁their ▁corresponding ▁" real " ▁particles . ▁ ▁Some ▁research ers ▁have ▁hoped ▁the ▁Lar ge ▁Had ron ▁Coll ider ▁at ▁C ER N ▁might ▁produce ▁evidence ▁for ▁the ▁existence ▁of ▁super part ner ▁particles . ▁However , ▁as ▁of ▁ 2 0 1 8 , ▁no ▁such ▁evidence ▁has ▁been ▁found . ▁
