Let ℓ > 3 be an odd prime and let A be an integer not divisible by ℓ. Let C A be the non‐singular projective model over ℚ of the affine curve C A : y 2 = x ℓ + A . In this paper, we use the theory of Hilbert modular Eisenstein series to obtain a formula for the central value of the Hasse–Weil L ‐function L ( C A , s ) of the curve C A when the cyclotomic field ℚ(ζ ℓ ) has ideal class number 1.
