Standard Model Confronting New Results for epsilon'/epsilon

We analyze the CP violating ratio \epe=epsilon'/epsilon in the Standard Model in view of the new KTeV results. We review the present status of the most important non-perturbative parameters B_6, B_8, B_K and of the strange quark mass m_s. We also briefly discuss the issues of final state interactions and renormalization scheme dependence. Updating the values of the CKM parameters, of m_t and Lambda (MSbar) and using Gaussian errors for the experimental input and flat distributions for the theoretical parameters we find \epe substantially below the NA31 and KTeV data: \epe= (7.7^{+6.0}_{-3.5}) 10^{-4} and \epe= (5.2^{+4.6}_{-2.7}) 10^{-4} in the NDR and HV renormalization schemes respectively. A simple scanning of all input parameters gives on the other hand 1.05 10^{-4} < \epe < 28.8 10^{-4} and 0.26 10^{-4} < \epe < 22.0 10^{-4} respectively. Analyzing the dependence on various parameters we find that only for extreme values of B_6, B_8 and m_s and suitable values of CKM parameters and Lambda(MSbar), the ratio \epe can be made consistent with data. We analyze the impact of these data on the lower bounds for Im(V_{td}V_{ts}^*), Br(K_L to pi^0 nu barnu), Br(K_L to pi^0e^+e^-)_{dir} and on tan(beta) in the Two Higgs Doublet Model II.Comment: main latex-file, 4 figures and related latex files, 47 page

Séquence de dépôts binaire et discontinuités associées Binary Sequence of Deposits and Associated Discontinuities

Une séquence de dépôts binaire a été élaborée à partir d’observations de terrain. Elle s’applique à différentes échelles et à différents milieux de dépôts. La séquence binaire est composée de deux séquences. Chacune d’elles est subdivisée en deux cycles. Les cycles inférieurs représentent les 3/5e en durée et les cycles supérieurs les 2/5e. Au total, cela fait quatre cycles. Dans le détail, cette séquence binaire comprend dix termes de faciès délimités par dix discontinuités dont quatre sont importantes. Ces dernières délimitent les quatre cycles. On distingue deux « maximum flooding surface » (m.f.s.) au centre des deux cycles supérieurs. <br> A binary sequence of deposits was elaborate starting from the observations of ground. It applies to various scales and various of deposits media. The binary sequence is made up of two sequences. Each sequence is subdivided in two cycles. The lower cycles account for the three fifths in duration and the higher cycles the remaining two fifths. On the whole, that made four cycles. In detail, this binary sequence includes ten terms of facies delimited by ten discontinuities of which four among they are significant. These last delimit the four cycles. One distinguishes two m.f.s. or maximum flooding surface in the center from the two higher cycles
