Query: Dressed elliptic genus of heterotic compactifications with torsion and
  general bundles   We define and compute the dressed elliptic genus of N = 2 heterotic
compactifications with torsion that are principal two-torus bundles over a K3
surface. We consider the most general gauge bundle compatible with
supersymmetry, a stable holomorphic vector bundle over the base together with
an Abelian bundle over the total space, generalizing the computation previously
done by the authors in the absence of the latter. Starting from a (0,2) gauged
linear sigma-model with torsion we use supersymmetric localization to obtain
the result. We provide also a mathematical definition of the dressed elliptic
genus as a modified Euler characteristic and prove that both expressions agree
for hypersurfaces in weighted projective spaces. Finally we show that it admits
a natural decomposition in terms of N = 4 superconformal characters, that may
be useful to investigate moonshine phenomena for this wide class of N = 2
vacua, that includes K3*T2 compactifications as special cases.
