DESCRIPTION:Scattering amplitudes are often split up into their gauge (su(
N)) and kinematic (two copies of complexified su(2)) components. Since the
su(N) gauge part is often calculated using flows of colour\, it should si
milarly be possible to describe the su(2) \\oplus su(2) kinematics of an a
mplitude in terms of flows of chirality. In two recent papers (hep-ph:2003
.05877 & hep-ph:2011.10075) we showed that this is indeed the case\, intro
ducing the chirality-flow formalism for Standard Model calculations. In th
e chirality-flow method (which simplifies the spinor-helicity method) Feyn
man diagrams can be directly written down in terms of Lorentz-invariant sp
inor inner products\, allowing the simplest and most direct possible path
from Feynman diagram to complex number. In this talk\, I will introduce th
is method and show some examples.\n\nhttps://agenda.irmp.ucl.ac.be/event/4
