At the LHC, combinatorics make it unlikely that we will be able to observe stop
pair production with a decay to a semileptonic top pair and missing energy.
Using a Standard-Model top tagger on fully hadronic top decays we can not only
extract the stop signal but also measure the top momentum.
To illustrate the promise of tagging tops with moderate boost we include a
detailed discussion of...

CDF presents improved bounds on the CP-violating phase beta_s and on the decay-width difference DeltaGamma_s of the neutral B0_s meson system. We use 6500 B0_s --> J/psi phi decays collected by the dimuon trigger and reconstructed in a sample corresponding to 5.2 fb^{-1} of data. Besides exploiting a two-fold increase in statistics with respect to the previous measurement, several improvements...

We present a search for a low mass standard model Higgs boson in
proton-antiproton collisions at a center-of mass energy of 1.96 TeV
with the D0 detector at the Fermilab Tevatron collider. The
search is performed using the associated production of
the Higgs boson with a W or a Z boson which decay, resulting
in final state with one or two b-tagged jets in association
with either two...

We present a search for Higgs bosons in bh(-->bb) and bbh(-->bb) channels
at a center-of-mass energy of 1.96 TeV using up to 6.3 fb-1 opf data
collected with the D0 detector at the Fermilab Tevatron collider.
In many supersymmetric models the cross-section for the production
of neutral Higgs bosons in association with bottom quarks is greatly
enhanced compared to the standard model and...

Using 5.4 fb-1 of data from ppbar collisions at sqrt(s)=1.96 TeV recorded
with the D0 detector at the Fermilab Tevatron collider we investigate
various models of new physics using final states with new long-lived
particles. We investigate models in which charged massive long-lived
particles are pair produced, as well as models in which a single heavy
ionizing state is observed in the...

One of the major goals at the LHC will be the search for Higgs boson(s). Once found, ambitious measurements and analyses will have to be performed in order to establish experimentally the Higgs mechanism as being responsible for the creation of particle masses without violating gauge principles.
I will present the composite Higgs model as a possible alternative to the elementary Higgs...
