  1. Worldsheet methods for perturbative quantum field theory

    … the study of the ambitwistor string and the scattering equations, while the second concerns the interplay of the symmetries of the asymptotic null boundary of Minkowski space, called $\scri$, and scattering amplitudes. The first part begins with a review of the CHY formulas for scattering

  2. Études in Ambitwistor Strings - Exploring new models, higher loops and curved backgrounds

    We begin with an overview of the scattering equations, CHY formalism and the ambitwistor string. We discuss one of the striking simplifications that occur upon restricting to four spacetime dimensions, namely that the scattering equations with $n$ particles decompose into sectors, graded by an …

  3. The measurement of the output spectrum of a cobalt 60 teletherapy unit

    … radiation from this beam, at each of a number of scattering angles, was therefore measured. This scattered spectrum was then converted to the output spectrum by the application of the appropriate scattering equations. The measured spectrum was corrected for crystal and photomultiplier tube …

  4. Ab initio approaches to nuclear structure and scattering

    … in applying it to describe non-relativistic scattering states and reactions in the continuum despite recent progress. To address those difficulties, a simplification of the harmonic oscillator representation of scattering equations (HORSE) technique developed earlier, the single-state HORSE …
