Review articles tend to fall into two categories: either they are unbiased and comprehensive
with a list of references including every paper on the subject; or else they are selective …

Supergravity was discovered four years ago [234,120, 235] and interest in this new theory
has been great from the beginning. However, the rapid development of the field and various …

A bstract Quantum scattering amplitudes for massive matter have received new attention in
connection to classical calculations relevant to gravitational-wave physics. Amplitude …

We give a review of conformal supergravity considered as a candidate for a fundamental
theory describing physics at Planck distances. Conformal supergravities are supersymmetric …

An attempt is made to construct a realistic model of particle physics based on eleven-
dimensional supergravity with seven dimensions compactified. It is possible to obtain an SU …

We show that, despite a widespread belief, the gravitational interaction of massless higher-
spin fields (s> 2) does exist at least in the first nontrivial order. The principal novel feature of …

A cubic interaction of all massless higher-spin fields with s⩾ 1 is constructed, based on the
extended higher-spin superalgebras suggested previously by one of us (MV). This …

A new class of R 2 type of actions without ghosts and tachyons is found in which both the
vierbein field e μ a and the spin connection ω μ ab are independent and propagating fields …

We construct the spin-projection operators for a theory containing a symmetric two-index
tensor and a general three-index tensor. We then use them to analyze, at linearized level …

Massive spin s⩾ 3/2 fields can become partially massless in cosmological backgrounds. In
the plane spanned by m2 and Λ, there are lines where new gauge invariances permit …
