Truncated cluster algebras and Feynman integrals with algebraic letters

  title={Truncated cluster algebras and Feynman integrals with algebraic letters},
  author={Song He and Zhenjie Li and Qinglin Yang},
We propose that the symbol alphabet for classes of planar, dual-conformalinvariant Feynman integrals can be obtained as truncated cluster algebras purely from their kinematics, which correspond to boundaries of (compactifications of) G+(4, n)/T for the n-particle massless kinematics. For one-, two-, three-mass-easy hexagon kinematics with n = 7, 8, 9, we find finite cluster algebras D4, D5 and D6 respectively, in accordance with previous result on alphabets of these integrals. As the main… Expand

Comments on all-loop constraints for scattering amplitudes and Feynman integrals
We comment on the status of “Steinmann-like” constraints, i.e. allloop constraints on consecutive entries of the symbol of scattering amplitudes and Feynman integrals in planar N = 4Expand
The elliptic double box and symbology beyond polylogarithms
We study the elliptic double-box integral, which contributes to generic massless QFTs and is the only contribution to a particular 10-point scattering amplitude in N = 4 SYM theory. Based on aExpand
