In this paper we obtain for T+, a one-sided singular integral given by a\nCalder 'on-Zygmund kernel with support in (-\∞,0), a Lp(w) bound when\nw\∈ A1+. A. K. Lerner, S. Ombrosi, and C. P 'erez proved in [ "A1\nBounds for Calder 'on-Zygmund operators related to a problem of Muckenhoupt and\nWheeden", Math. Res. Lett. \16 (2009), no. 1, 149-156] that this bound\nis sharp with respect to ||w||A1 and p . We also give a\nL1,\∞(w) estimate, for a related problem of Muckenhoupt and Wheeden\nfor w\∈ A1+ . We improve the classical results, for one-sided singular\nintegrals, by putting in the inequalities a wider class of weights.\n
