Polarization and Resummation in Slepton Production at Hadron Colliders
In R-parity conserving supersymmetric (SUSY) models, sleptons are produced in pairs at hadron colliders through neutral and charged electroweak currents. We demonstrate that the polarization of the initial hadron beams allows for a direct extraction of the slepton mixing angle and thus for a determination of the underlying SUSY-breaking mechanism. We also perform a first precision calculation o...
متن کاملTransverse Polarization Signatures of Extra Dimensions at Linear Colliders
If significant longitudinal polarization of both the electrons and positrons becomes feasible at a future linear collider(LC), it may be possible to use spin rotators to produce transversely polarized beams. Using the transverse polarization of both beams, new azimuthal spin asymmetries can be formed which will be sensitive probes for new physics beyond the Standard Model. Here we demonstrate t...
متن کاملThe Interference Effect of Top Quark Polarization at Hadronic Colliders
We derive a simple analytic expression for q ¯ q, gg → t ¯ t → bW + ¯ bW − → b ¯ lν l ¯ bl ′ ¯ ν l ′ for on shell intermediate states with the interference effects due to the polarizations of the t and ¯ t. We then investigate how this effect may be measured at Tevatron or other hadronic colliders.
متن کاملMore Transverse Polarization Signatures of Extra Dimensions at Linear Colliders
Polarization of both electron and positron beams at a future linear collider (LC) allows for the measurement of transverse polarization asymmetries. These asymmetries have been shown to be particularly sensitive to graviton or other spin-2, s−channel exchanges in the process e+e− → f f̄ (f = e) which allows for a doubling of the usual search reach. A question then arises as to whether other e+e−...
متن کاملΤ Polarization and Randall-sundrum Scenario at E
We study polarized cross-sections and forward-backward asymmetry for the process e+e− → τ+τ− in the stabilized Randall-Sundrum scenario. It is shown that there is substantial deviation from the Standard Model predictions, both in terms of the actual numerical values and angular distributions. The hierarchy between the electroweak and the Planck scale remains to be a mystry till date. Many possi...
