The $W_R$ production in $e\gamma$ collisions
We consider the production of a single right-handed gauge boson $W_R$ in the high-energy $e^-\gamma$ collisions with polarized beams. If the associated neutrino is light, the reaction will give the best discovery reach for $W_R$ in the Next Linear Collider.
LBNO-DEMO: Large-scale neutrino detector demonstrators for phased performance assessment in view of a long-baseline oscillation experiment
In June 2012, an Expression of Interest for a long-baseline experiment (LBNO) has been submitted to the CERN SPSC. LBNO considers three types of neutrino detector technologies: a double-phase liquid argon (LAr) TPC and a magnetised iron detector as far detectors. For the near detector, a high-pressure gas TPC embedded in a calorimeter and a magnet is the baseline design. A mandatory milestone is a concrete prototyping effort towards the envisioned large-scale detectors, and an accompanying campaign of measurements aimed at assessing the detector associated systematic errors. The proposed $6\times 6\times 6$m$^3$ DLAr is an industrial prototype of the design discussed in the EoI and scalable…
Single W-boson production in e-\gamma colliders
Single $W$-boson production in $e^-\gamma$ collisions with polarized beams is investigated. In the framework of the Standard Model the updated estimates for the measurement precision of photon anomalous coupling parameters $ \kappa_{ \gamma},$ $ \lambda_{ \gamma}$ at the Next Linear Collider with $ \sqrt{s_{ e\gamma }}=420$ GeV are obtained. The production of right-handed gauge bosons $ W^-_{ 2 }$ in this collision mode is also analysed. If the associated neutrino is light, the channel would give the best discovery reach for $ W^-_{ 2 }$ in the Next Linear Collider.
