Description
Spinning particles are models for point particles with spin degrees of freedom. They automatically feature N-supersymmetry on the worldline, with fixed albeit arbitrary N. After first quantization one obtains spin-N/2 states in the Hilbert space. Consistency conditions for second quantization, realized in the form of BRST quantization, can severely restrict the background fields in target space, putting them on-shell. In the N=2 case the target space can host a Yang-Mills gauge theory, while in N=4 it is possible to have Einstein's gravity and the NS-NS sector of Supergravity.
After explaining these passages, I will present new results involving the Ramond-Ramond fluxes (based on arXiv:2206.03243 with I. Sachs). I wish to conclude this analysis with some brief comments on almost complex structures (on-going work with O. Hulik and I. Sachs).
