We study generating series of Gromov–Witten invariants of E×ℙ 1 and their tropical counterparts. Using tropical degeneration and floor diagram techniques, we can express the generating series as sums of Feynman integrals, where each summand corresponds to a certain type of graph which we call a 𝑝𝑒𝑎𝑟𝑙𝑐ℎ𝑎𝑖𝑛. The individual summands are – just as in the case of mirror symmetry of elliptic curves, where the generating series of Hurwitz numbers equals a sum of Feynman integrals – complex analytic path integrals involving a product of propagators (equal to the Weierstrass-℘-function plus an Eisenstein series). We also use pearl chains to study generating functions of counts of tropical curves in E 𝕋 ×ℙ 𝕋 1 of so-called \textit{leaky degree}.
