Classical BV cohomology of the spinning particle
Eugenia Boffo, Martin Cederwall
We show that the classical Batalin--Vilkovisky cohomology at negative ghost number of the spinning particle, observed in ref. arXiv:1511.02135, is removed by a Koszul--Tate resolut…

BCOV on the Large Hilbert Space
Eugenia Boffo, Ondřej Hulík, Ivo Sachs
We formulate the BCOV theory of deformations of complex structures as a pull-back to the super moduli space of the worldline of a spinning particle. In this approach the appearance…

On Spinning Particles, their Partition Functions and Picture Changing Operators
Eugenia Boffo, Pietro Antonio Grassi, Ondřej Hulík +1
We compute the partition function for the spinning particle, including pictures and the large Hilbert space, and show that it counts the dimension of the BRST cohomology in t…
