Use of transverse beam polarization to probe anomalous V V H interactions at a Linear Collider
We investigate use of transverse beam polarization in probing anomalous coupling of a Higgs boson to a pair of vector bosons, at the International Linear Collider (ILC). We consider the most general form of V V H (V = W/Z) vertex consistent with Lorentz invariance and investigate its effects on the process ee → f f̄H, f being a light fermion. Constructing observables with definite CP and naive t...
متن کاملPositron Polarization at the International Linear Collider
We review some recent arguments supporting the upgrade of the International Linear Collider by a polarized positron beam, in addition to the polarized electron beam. The examples presented here mainly focus on the impact of positron polarization on items relevant to new physics searches, such as the identification of novel interactions in fermion-pair production and the formulation of new CP-se...
متن کاملAssessing the Merits of Positron Polarization at a Linear Collider
The possibility of polarized positron beams at a future linear collider has created much interest. At the 2001 Snowmass meeting, a study group (designated E3) included a subgroup whose charge was to closely examine the merits, as quantitatively as possible, of this option. The leading issues are outlined here, and a few physics examples are given. The deciding issues are, however, likely to be ...
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 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−...
