Input notation
l or ell→ ℓ (loop momentum)
l1, l2→ ℓ1, ℓ2
p, p1, p2→ p, p1, p2
s12, s23→ s12, s23 (Mandelstam)
m_H, M_W, m1→ mass labels (use _ for subscript)
l.p→ ℓ · p (dot product → CenterDot)
l*p→ ℓ p (scalar multiplication)
(l+p)^2→ (ℓ + p)²
1/2→ ½ (fraction)
-> or =→ → (substitution rule)
Output variables
mm, mm1, mmH= internal (propagator) mass²
MM, MM1, MMW= external momentum squared
s12, s23= Mandelstam invariants
Mass label mapping: m_H → output variable mmH; M_W → MMW.
Use output variable names in substitution rules, e.g. {mmH -> 1, s12 -> 6}.
Custom momentum & mass labels from your diagram are recognized automatically.
