    Oral
    The Universal Extra Dimension models are supposed to mimic SUSY at colliders. They are also of interest as a source of cold dark matter. I discuss how ILC can discriminate between UED and SUSY from lepton pair production. I will also discuss how, in UED, single production of n=2 electroweak gauge bosons as s-channel resonances (much in the same vein as LEP) may lead to a precision study...

  4. 92. Transverse polarization and new physics in gamma Z and Higgs Z production

    Oral
    Transverse polarization of electron and positron beams can be useful because it permits the use of azimuthal asymmetries even when the final state consists of two particles. It is found that with the use of transverse polarization, a CP-odd and T-odd observable can be constructed when the final-state particles are self-conjugate. In the case of HZ production, this observable can be used to...

  5. 143. Probing space-time structure at new physics with polarized beams at ILC

    New Physics at TeV Scale & Electroweak Precision Test
    Oral
    We approach the issue of the discovery of new physics at high energies associated with the proposed International Linear Collider in the presence of longitudinal as well as transverse electron and positron beam polarization. We determine the beam polarization dependence and the angular distribution of a particle of arbitrary spin in a one-particle inclusive final state produced in e+e-...

  6. 109. Distinguishing New Physics Scenarios at ILC with Polarized Beams
    Alexander Pankov (Techn. Univ. of Gomel)

    New Physics at TeV Scale & Electroweak Precision Test
    Oral
    Numerous non-standard dynamics are described by contact-like effective interactions that can manifest themselves only through deviations of the cross sections from the Standard Model predictions. If one such deviation were observed, it should be important to definitely identify, to a given confidence level, the actual source among the possible non-standard interactions that in principle...

  7. 21. Event shape discrimination of supersymmetry from large extra dimensions at a linear collider
    Prof. Probir Roy (tata Institute of Fundamental Research)

    New Physics at TeV Scale & Electroweak Precision Test
    Oral
    The production of a charged lepton ($\ell = e,\mu$) pair with a large missing energy at a linear collider is discussed as a means of distinguishing the minimal supersymmetry (MSSM) scenario from that with large extra dimensions (ADD) for parameter ranges where the total cross-sections are comparable for both. Analyses in terms of event shape variables, specifically sphericity and thrust,...

  8. 3. Precise Predictions for M_W in the MSSM with complex Parameters
    Dr Sven Heinemeyer (University of Zaragoza)

    New Physics at TeV Scale & Electroweak Precision Test
    Oral
    We present the currently most complete calculation of the W boson mass in the MSSM. We include a full one-loop calculation, for the time also for complex parameters, the full available SM result as well as all available MSSM two-loop corrections. In a numerical analysis we show the effect of the complex phases and the results for M_W in various MSSM scenarios.

  9. 78. Littlest Higgs Model and W pair production at ILC
    Dr Poulose Poulose (IIT Guwahati)

    New Physics at TeV Scale & Electroweak Precision Test
    Oral
    Among the viable alternatives to the Standard Higgs Mechanism is the recently proposed Little Higgs models. The advantage here is that the model has an elementary light neutral scalar particle without the hierarchy problem. The model has two heavy charged gauge bosons W_H and one heavy neutral gauge boson, Z_H, in addition to the standard W and Z. We have investigated the W pair...

  10. 110. Neutrino masses and the decay of triplet Higgs in the Littlest Higgs scenario
    Raghavendra Srikanth (Harish-Chandra Research Institute)

    New Physics at TeV Scale & Electroweak Precision Test
    Oral
    We investigate the sources of neutrino mass generation in Little Higgs theories, by confining ourselves to the Littlest Higgs scenario. Our conclusion is that the most satisfactory way of incorporating neutrino masses is to include a lepton-number violating interaction between the scalar triplet and lepton doublets. The tree-level neutrino masses are generated by the vacuum expectation...
