Query: Complete Form Factors in Yang-Mills from Unitarity and Spinor Helicity
  in Six Dimensions   We present a systematic procedure to compute complete, analytic form factors
of gauge-invariant operators at loop level in pure Yang-Mills. We consider
applications to operators of the form $\mathrm{Tr}\, F^n$ where $F$ is the
gluon field strength. Our approach is based on an extension to form factors of
the dimensional reconstruction technique, in conjunction with the
six-dimensional spinor-helicity formalism and generalised unitarity. For form
factors this technique requires the introduction of additional scalar
operators, for which we provide a systematic prescription. We also discuss a
generalisation of dimensional reconstruction to any number of loops, both for
amplitudes and form factors. Several novel results for one-loop minimal and
non-minimal form factors of $\mathrm{Tr}\, F^n$ with $n>2$ are presented.
Finally, we describe the \texttt{Mathematica} package
\texttt{SpinorHelicity6D}, which is tailored to handle six-dimensional
quantities written in the spinor-helicity formalism.
