Title: Branon radiative corrections to collider physics and precision observables

Abstract

In the context of brane-world scenarios, we study the effects produced by the exchange of virtual massive branons. A one-loop calculation is performed which generates higher-dimensional operators involving SM fields suppressed by powers of the brane tension scale. We discuss constraints on this scenario from colliders such as HERA, LEP and Tevatron and prospects for future detections at LHC or ILC. The most interesting phenomenology comes from new four-particles vertices induced by branon radiative corrections, mainly from four-fermion interactions. The presence of flexible branes modifies also the muon anomalous magnetic moment and the electroweak precision observables.

  • We calculate the two-loop QCD correction to the scalar quark contributions to the electroweak gauge-boson self-energies at zero momentum transfer in the supersymmetric extension of the standard model (SM) and derive the associated O({alpha}{sub s}) correction to the {rho} parameter. The two-loop corrections modify the one-loop contribution by up to 30{percent} the gluino decouples for large masses. Contrary to the SM case where the QCD corrections are negative and screen the one-loop value, the corresponding corrections in the supersymmetric case are in general positive, increasing the sensitivity in the search for scalar quarks through their virtual effects in high-precision electroweakmore » observables. {copyright} {ital 1997} {ital The American Physical Society}« less
  • Lowest-order electromagnetic corrections to the hadron current in the deep-inelastic scattering of polarized leptons by polarized nucleons are calculated in the quark-parton model. The results of numerical calculation of these corrections to the cross section and polarization asymmetries for experiments with a fixed target are analyzed. 19 refs., 7 figs.
  • Different electroweak observables probe different combinations of the parameters {bar {theta}} (the weak mixing angle as defined in terms of couplings at the {ital Z} pole) and {rho}{identical to}{ital M}{sub {ital W}}{sup 2}/({ital M}{sub {ital Z}}{sup 2}cos{sup 2}{bar {theta}}). A simple, approximate method is given for relating these parameters to the angle {theta} defined in terms of gauge-boson masses by cos{sup 2}{theta}{identical to}{ital M}{sub {ital W}}{sup 2}/{ital M}{sub {ital Z}}{sup 2}, and it is shown how these various observables shed light on {theta} and quantities such as the top-quark mass that directly affect {rho}.
  • The model-independent QED radiative corrections to polarization observables in elastic scattering of unpolarized and longitudinally polarized electron beams by a deuteron target are calculated in leptonic variables. The experimental setup when the deuteron target is arbitrarily polarized is considered and the procedure for applying the derived results to the vector or tensor polarization of the recoil deuteron is discussed. The calculation is based on taking all essential Feynman diagrams into account, which results in the form of the Drell-Yan representation for the cross section, and the use of the covariant parameterization of the deuteron polarization state. Numerical estimates of themore » radiative corrections are given in the case where event selection allows undetected particles (photons and electron-positron pairs) and the restriction on the lost invariant mass is used.« less
  • We present the analytical and numerical results for the Dalitz plot and the {beta} energy spectrum of charged and neutral-hyperon semileptonic decays in two approximations. Two illustrative processes {Sigma}{sup {minus}}{r_arrow}{ital ne}{bar {nu}} and {Lambda}{r_arrow}{ital pe}{bar {nu}} in which the {ital q} (momentum transfer) is not negligible are considered.
