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...

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...

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-...

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...

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,...

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.

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...

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...
