Title: Quantum quenches near a quantum critical point in 1+1 dimensions

ABSTRACT: I'll review the perturbative formalism to quantum quenches
near a quantum critical point in 1+1 dimensions introduced in [1].
I'll then provide explict applications of it to the  Ising and the XYZ
spin chain. I will finally argue how the mass spectrum of a theory can
be inferred from quantum  dynamical experiments and Fourier analysis:
these considerations notably apply to the spectrum of Ising field
theory in a magnetic field (Zamolodchikov "E8" spectrum).
