We systematically study the first three terms in the asymptotic expansions of the moments of the transmission eigenvalues and proper delay times as the number of quantum channels n in the leads goes to infinity. The computations are based on the assumption that the Landauer-Buttiker scattering matrix for chaotic ballistic cavities can be modelled by the circular ensembles of random matrix theory. The starting points are the finite-n formulae that we recently discovered [F. Mezzadri and N. J. Simm, Moments of the transmission eigenvalues, proper delay times and random matrix theory, J. Math. Phys. 52, 103511 (2011)]. Our analysis includes all the symmetry classes beta is an element of {1, 2, 4}; in addition, it applies to the transmission eigenvalues of Andreev billiards, whose symmetry classes were classified by Zirnbauer [Riemannian symmetric superspaces and their origin in random-matrix theory, J. Math. Phys. 37(10), 4986 (1996)] and Altland and Zirnbauer [Random matrix theory of a chaotic Andreev quantum dot, Phys. Rev. Lett. 76(18), 3420 (1996); Nonstandard symmetry classes inmesoscopic normal-superconducting hybrid structures, Phys. Rev. B 55(2), 1142 (1997)]. Where applicable, our results are in complete agreement with the semiclassical theory of mesoscopic systems developed by Berkolaiko et al. [Full counting statistics of chaotic cavities from classical action correlations, J. Phys. A: Math. Theor. 41(36), 365102 (2008)] and Berkolaiko and Kuipers [Moments of the Wigner delay times, J. Phys. A: Math. Theor. 43(3), 035101 (2010); Transport moments beyond the leading order, New J. Phys. 13(6), 063020 (2011)]. Our approach also applies to the Selberg-like integrals. We calculate the first two terms in their asymptotic expansion explicitly. (C) 2012 American Institute of Physics. [http://dx. doi.org/10.1063/1.4708623]
