    We define finite rank for Zᵈ actions and show that those finite rank actions with a certain tower shape are loosely Bernoulli for d ≥ 1

    Even Kakutani Equivalence And The Loose Block Independence Property For Positive Entropy Zᵈ Actions

    Get PDF
    In this paper we define the loose block independence property for positive entropy Zᵈ actions and extend some of the classical results to higher dimensions. In particular, we prove that two loose block independent actions are even Kakutani equivalent if and only if they have the same entropy. We also prove that for d \u3e 1 the ergodic, isometric extensions of the positive entropy loose block independent Zᵈ actions are also loose block independent

    Directional Recurrence For Infinite Measure Preserving Zᵈ Actions

    Get PDF
    We define directional recurrence for infinite measure preserving Zd actions both intrinsically and via the unit suspension flow and prove that the two definitions are equivalent. We study the structure of the set of recurrent directions and show it is always a Gδ set. We construct an example of a recurrent action with no recurrent directions, answering a question posed in a 2007 paper of Daniel J. Rudolph. We also show by example that it is possible for a recurrent action to not be recurrent in an irrational direction even if all its sub-actions are recurrent

    Anomalous WWgamma couplings in gamma-proton collision at the LHC

    Full text link
    We examine the potential of pp-> p gamma p -> p W q X reaction to probe anomalous WWgamma couplings at the LHC. We find 95% confidence level bounds on the anomalous coupling parameters with various values of the integrated luminosity. We show that the reaction pp -> p gamma p -> p W q X at the LHC highly improve the current limits.Comment: 12 pages,3 figure

    Resonant production of diquarks at high energy pp, ep and e+e- colliders

    Full text link
    Resonant productions of the first generation scalar and vector diquarks at high energy hadron-hadron (pp), lepton-hadron (ep) and lepton-lepton (e+e-) colliders are investigated. Taking into account the hadronic component of the photon, diquarks can be produced resonantly in the lepton-hadron and lepton-lepton collisions. Production rates, decay widths and signatures of diquarks are discussed using the general, SU(3)_{C} x SU(2)_{W} x U(1)_{Y} invariant, effective Lagrangian. The corresponding dijet backgrounds are examined in the interested invariant mass regions. The attainable mass limits and couplings are obtained for the diquarks that can be produced in hadron collisions and in resolved photon processes. It is shown that hadron collider with center of mass energy sqrt(s)=14 TeV will be able to discover scalar and vector diquarks with masses up to m_{DQ}=9 TeV for quark-diquark-quark coupling alpha_{DQ}=0.1. Relatively, lighter diquarks can be probed at ep and e+e- collisions in more clear environment.Comment: 12 pages, 12 figures, 6 table

    Rank One And Loosely Bernoulli Actions In Zᵈ

    Get PDF
    We define rank one for Zᵈ actions and show that those rank one actions with a certain tower shape are loosely Bernoulli for d greater than or equal to 1. We also construct a zero entropy Z² loosely Bernoulli action with a zero entropy, ergodic, non-loosely Bernoulli one-dimensional subaction
