Mass formula for $\Lambda$ hypernuclei based on SU(6) symmetry
G. Lévai, J. Cseh, P. Van Isacker1, O. Juillet1
(1998)

An extension of the Weizsäcker mass formula is proposed for the simultaneous description of normal (i.e. non-strange) nuclei and {LAMBDA} hypernuclei. The mass formula is inspired by the spin–flavour SU(6) symmetry of Gürsey and Radicati and includes a Majorana term. Available masses of normal nuclei and Image hypernuclei are analysed with the formula. It is found that the Majorana term successfully replaces the conventional pairing term.
