Description
Taylor expansion of the equation of state of QCD
suffers from shortcomings at chemical potentials $\mu_B \geq (2-2.5)T$.
First, one faces difficulties inherent in performing such an expansion
with a limited number of coefficients; second,
higher order coefficients determined from
lattice calculations suffer from a poor signal-to-noise ratio.
We present a novel scheme for extrapolating
the equation of state of QCD to finite, real chemical
potential that can extend its reach further than previous methods.
We show continuum extrapolated lattice results for the new
expansion coefficients and for the thermodynamic observables up
to $\mu_B/T\le3.5$.
