Parameters
Veneziano (1968):
A(s,t) = B(−α(s), −α(t))
= Γ(−α(s))Γ(−α(t))/Γ(−α(s)−α(t))
Regge trajectory:
α(s) = α₀ + α's
Poles at α(s)=n → particles!
Regge trajectories:
J = α₀ + α' M²
Slope = α' = 1/(2πT_s)
Tension T_s ~ (440 MeV)²
Duality:
s-channel resonances = t-channel Regge exchange — "Venice" triumph.
