Query: Quantizing the rotating string with massive endpoints   We compute leading order quantum corrections to the Regge trajectory of a
rotating string with massive endpoints using semiclassical methods. We expand
the bosonic string action around a classical rotating solution to quadratic
order in the fluctuations and perform the canonical quantization of the
resulting theory. For a rotating string in $D$ dimensions the intercept
receives contributions from $D-3$ transverse modes and one mode in the plane of
rotation, in addition to a contribution due to the Polchinski-Strominger term
of the non-critical effective string action when $D\neq26$. The intercept at
leading order is proportional to the expectation value of the worldsheet
Hamiltonian of the fluctuations, and this is shown explicitly in several cases.
All contributions to the intercept are considered, and we show a simple
physical method to renormalize the divergences in them. The intercept converges
to known results at the massless limit, and corrections from the masses are
explicitly calculated at the long string limit. In the process we also
determine the quantum spectrum of the string with massive endpoints, and
analyze the asymmetric case of two different endpoint masses.
