We present a prototype version of a new, fully differential ttbar
threshold event generator based on NNLO(NNLL) QCD calculations.
We will describe how the generator is structured, the use of an
interpolation scheme that is the only practical solution to make it
usable in terms of CPU resources, and the use of up to date methods
for the inclusion of the ILC luminosity spectrum....

The main technical difficulties associated with measurement of the top quark
threshold are from uncertainties in the luminosity spectrum due to the large
beamstrahlung and the determination of absolute beam energy of the two
beams. We present the ongoing developments to measure both the beam
energy using electron beam diagnostics and the luminosity spectrum using
the acollinearity of...

Single top quark production is expected to be an interesting process
for studies at both hadron and lepton colliders. A review on single top
production processes in e+e-, e-gamma and gamma-gamma collision
modes at a linear collider is presented. A special attention is paid to the
production cross sections, spin correlation properties, some aspects of
new physics via single top.

We analyse the associated production of the Higgs boson with a top quar pair,
${e^-e^+ \to t\bar t\Phi}$, in the most general case where the coupling
is a mixture of scalar and pseudoscalar components, $g_{\Phi t \bar t} \propto
(a+i b \gamma_5)$. We have calculated the individual helicity amplitudes for
the process and obtained the corresponding cross sections for each helicity
state;...

LCFI recently released the ZVTOP vertexing package which also
includes the b-tagging capabilities. The talk will review the
performance of the package in application to measurements of anomalous
couplings of the top quark. Variables which can distiguish between b and
bbar (ex vertex charge) will be especially useful to study asymmetries
sensitive to the top anomalous couplings.

We calculate the Born order cross-section for the exclusive production
of rho meson pairs in e+e- scattering in the Regge limit of QCD and we
show the feasibility of the measurement of this process at the ILC.
We also give a first estimate of the leading order BFKL evolution and
we show how this process could be considered as a clean test of the
BFKL resummation effects.
