Let d > 0 be a fundamental discriminant of a real quadratic field. Let h (d) be the class number and ε d the fundamental unit of the real quadratic field Q (d). In this paper, we prove that if there is an elliptic curve E over Q whose Hasse-Weil L -function L E / Q (s) has a zero of order g at s = 1 , then there is an effectively computable constant κ > 0 satisfying h (d) log ε d > 1 κ (log d) g − 3 ∏ p | d , p ≠ d (1 − ⌊ 2 p ⌋ p + 1).
