B Physics Prospects at LHC
Future Experiments at LHC will have the opportunity to pursue an extensive
program on B Physics and CP violation. The expected performance are presented
here.Comment: Presented at XXXXth Rencontres de Moriond, Electroweak Interaction
and Unified Theories, March 5-12, 200
Single Top Production as a Probe of B-prime Quarks
We show how single top production at the LHC can be used to discover (and
characterize the couplings of) B' quarks, which are an essential part of many
natural models of new physics beyond the Standard Model. We present the B'
effective model and concentrate on resonant production via a colored anomalous
magnetic moment. Generally, B's preferentially decay into a single top quark
produced in association with a W boson; thus, this production process makes
associated single top production essential to B' searches at the LHC. We
demonstrate the background processes are manageable and the signal cross
section is sufficient to yield a large signal significance even during the 7
TeV LHC run. Specifically, we show that B' masses of 700 GeV or more can be
probed. Moreover, if a B' is found, then the chirality of its coupling can be
determined. Finally, we present signal cross sections for several different LHC
energies.Comment: 19 pages, 7 figures, 1 tabl
Review of CP Violation Studies with B-Mesons at LHC
The Large Hadron Collider (LHC) proposed at CERN will be the ultimate source
of B-mesons. With the large number of B-mesons expected at LHC, a real
precision test of CP violation in B-meson decays will become possible. There
are already several efforts made to explore this possibility and a summary of
those activities is presented.Comment: Standard LaTex, No figure, 10 pages Plenary talk given at 1994

Detecting Higgs Bosons with Muons at Hadron Colliders
We investigate the prospects for the discovery of neutral Higgs bosons with a
pair of muons by direct searches at the CERN Large Hadron Collider (LHC) as
well as by indirect searches in the rare decay at the
Fermilab Tevatron and the LHC. Promising results are found for the minimal
supersymmetric standard model, the minimal supergravity (mSUGRA) model, and
supergravity models with non-universal Higgs masses (NUHM SUGRA). For
, we find that (i) the contours for a branching fraction
of in the parameter space are very
close to the contours for at the LHC with an integrated luminosity () of 30
fb, (ii) the regions covered by and the discovery region for with 300
fb are complementary in the mSUGRA parameter space, (iii) in NUHM SUGRA
models, a discovery of at the
LHC will cover regions of the parameter space beyond the direct search for
with fb.Comment: The version to appear in Physics Letters
CP-Violation in the Two Higgs Doublet Model: from the LHC to EDMs
We study the prospective sensitivity to CP-violating Two Higgs Doublet Models
from the 14 TeV LHC and future electric dipole moment (EDM) experiments. We
concentrate on the search for a resonant heavy Higgs that decays to a boson
and a SM-like Higgs h, leading to the final state. The
prospective LHC reach is analyzed using the Boosted Decision Tree method. We
illustrate the complementarity between the LHC and low energy EDM measurements
and study the dependence of the physics reach on the degree of deviation from
the alignment limit. In all cases, we find that there exists a large part of
parameter space that is sensitive to both EDMs and LHC searches.Comment: 21 pages, 34 figure
Probing the charged Higgs boson at the LHC in the CP-violating type-II 2HDM
We present a phenomenological study of a CP-violating two-Higgs-doublet Model
with type-II Yukawa couplings at the Large Hadron Collider (LHC). In the light
of recent LHC data, we focus on the parameter space that survives the current
and past experimental constraints as well as theoretical bounds on the model.
Once the phenomenological scenario is set, we analyse the scope of the LHC in
exploring this model through the discovery of a charged Higgs boson produced in
association with a W boson, with the former decaying into the lightest neutral
Higgs and a second W state, altogether yielding a b\bar b W^+W^- signature, of
which we exploit the W^+W^- semileptonic decays.Comment: 37 pages, 16 figures; v2 updated treatment of LHC constraint
Future B Experiments from The BTeV/LHC-b Perspective
Many measurements are necessary in the program of studying mixing, CP
violation and rare decays of b and c quarks. These measurements require large
numbers of B^o, B_s, B^- and D^{*+} hadrons. Fortunately, copius production of
particles containing b and c quarks will occur at Tevatron and the LHC. The
crucial measurements are described here, as well as the design of the two
experiments, LHC-b and BTeV, that can exploit the 4-20 x 10^{11} b hadrons
produced every 10^7 seconds.Comment: Presented at the 3rd International Conference on B Physics and CP
