As was the case in the parent 10-dimensional theory, 9-dimensional N = 1 supergravity contains a single supergravity multiplet and an arbitrary number of vector multiplets.

The structure of the pseudoscalar meson multiplet, and also the ground state baryon multiplets, led Gell-Mann ( and Zweig, independently ) to create the well known quark model.
23.
The strong interactions binding the quarks together are insensitive to these quantum numbers, so variation of them leads to systematic mass and coupling relationships among the hadrons in the same flavor multiplet.
24.
The Gell-Mann Okubo mass formula systematized the quantification of these small mass differences among members of a hadronic multiplet, controlled by the explicit symmetry breaking of SU ( 3 ).
25.
In 1949 she became the first woman elected as an associate of the Royal Astronomical Society of Great Britain, in honor of her work on multiplet tablets and in identifying solar spot electra.
26.
The highest component of a vector multiplet is a gauge boson, the highest component of a chiral or hypermultiplet is a spinor, the highest component of a gravity multiplet is a graviton.

The highest component of a vector multiplet is a gauge boson, the highest component of a chiral or hypermultiplet is a spinor, the highest component of a gravity multiplet is a graviton.
28.
The no-go theorems can be avoided, as was first discovered by Fradkin and Vasiliev, by switching on the cosmological constant and taking an infinite multiplet of higher-spin fields.
29.
When linearized these equations describe free massless fields of spins s = 0, 1, 2, 3, . . . . ( and super-symmetric extension of this multiplet ).
30.
In the 1950s and 1960s, the pseudoscalar mesons began to proliferate, and were eventually organized into a multiplet according to Murray Gell-Mann's so-called " Eightfold Way ".
