*Theory seminar*
Monday, March 15th, 1:00 PM

*Maxwell Hansen* (University of Edinburgh) will talk about "Three-pion
scattering from lattice QCD".


*Abstract:*

In this talk, I will present a lattice-QCD calculation of the
maximal-isospin, three-pion scattering amplitude (3π+ to 3π+). The
calculation combines finite-volume energies with a relativistic
field-theoretic formalism, required to interpret the results. I will
describe the full work-flow required to reach the final amplitude,
implemented here for the first time, and discuss the complicated
singularities appearing in the latter. Finally I will discuss prospects for
applying these methods to resonant three-particle systems, in order to gain
a deeper understanding of these complicated objects from first principles
QCD.

We look forward to seeing you at the seminar!
Astrid, Christos, Filippo
