Query: A Novel Foamy Origin for Singlet Fermion Masses   We show how masses for singlet fermions can be generated by interactions with
a D-particle model of space-time foam inspired by brane theory. It has been
shown previously by one of the authors (N.E.M.) such interactions may generate
generate dynamically small masses for charged fermions via the recoils of
D-particle defects interacting with photons. In this work we consider the
direct interactions of D-particle with uncharged singlet fermions such as
right-handed neutrinos. Quantum fluctuations of the lattice of D-particles have
massless vector (spin-one) excitations that are analogues of phonons. These
mediate forces between the singlet fermions, generating large dynamical masses
that may be communicated to light neutrinos via the seesaw mechanism.
