On search for new Higgs physics in CDF at the Tevatron
We discuss the Higgs boson mass sum rules in the Minimal Supersymmetric
Standard Model in order to estimate the upper limits on the masses of stop
quarks as well as the lower bounds on the masses of the scalar Higgs boson
state. The bounds on the scale of quark-lepton compositeness derived from the
CDF Collaboration (Fermilab Tevatron) data and applied to new extra gauge boson
search is taken into account. These extra gauge bosons are considered in the
framework of the extended SU(2)_h \times SU(2)_l model. In addition, we discuss
the physics of rare decays of the MSSM Higgs bosons in both CP-even and CP-odd
sectors and also some extra gauge bosons.Comment: 24 pages, LaTeX, 8 figure
Lepton flavor violation decays in the topcolor-assisted technicolor model and the littlest Higgs model with parity
The new particles predicted by the topcolor-assisted technicolor ()
model and the littlest Higgs model with T-parity (called model) can
induce the lepton flavor violation () couplings at tree level or one loop
level, which might generate large contributions to some processes. Taking
into account the constraints of the experimental data on the relevant free
parameters, we calculate the branching ratios of the decay processes
with = , and
in the context of these two kinds of new physics models. We find
that the model and the model can indeed produce significant
contributions to some of these decay processes.Comment: 24 pages, 7 figure
Some Uses and Potentials of Qualitative Methods in Planning
Planners use methods borrowed from many disciplines. These are usually modified and adapted to meet planner's needs to acquire and sift through many diverse information sources helpful in dealing with complex problems. The quantitative methods which planners use are well known, well established in practice, and acknowledged by most as tools of the planners' trade. In contrast to this, most planners also use qualitative methods but these are rarely explicitly acknowledged.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68912/2/10.1177_0739456X8600600110.pd
