\section{Interplay of flavor and high~$p_T$ physics}
\label{sec:B:interplay}

In this section we want to report some result of the recent
workshops ``Flavour in the LHC era''~\cite{delAguila:2008iz,Buchalla:2008jp,Raidal:2008jk} from the
perspective of \superb.

We have already commented on the complementarity of the
physics goals of flavor and high~$p_T$ physics, which are
both necessary to identify the structure of the New Physics models.

Three analyses out of these reports should demonstrate the importance of
the interplay in our future new physics search:

In the context of this workshop the study of several SUSY-breaking models,
along the same lines of the previous section, have been presented to show
the capability of combined flavor and high~$p_T$ data in identifying the
SUSY-breaking mechanism.

Another study that started at the workshop concerns the effects of
flavor violation on direct searches at LHC, which are often not fully
taken into account.
It has been shown that flavor violation could, in some cases,
change the decay chains used at LHC to reconstruct the New Physics mass
spectrum, possibly making the analysis more involved~\cite{delAguila:2008iz,Hurth:2003th}.

The workshop result most relevant to Super$B$ physics comes from
a first attempt at combining of flavor and high~$p_T$ physics on the
same New Physics parameter space.
Based on existing flavor physics and high-energy computer codes,
a so-called master tool was developed which combines calculations from
both low-energy and electroweak observables in one common code.
The details of the analysis presented at the workshop can
be found in~\cite{Buchalla:2008jp}.

The complementarity of flavor physics and high~$p_T$ physics is
shown in Figure ~\ref{fig:tanbeta_a}. It is clearly demonstrated that,
without the inclusion of  both the flavor and
electroweak constraints, the parameters  $\tan\beta$ and $M_A$ are much
less well-determined. It can be seen, as well, that LHC mainly constrains the
mass, whereas flavor physics constrains the flavor coupling (\ie\
~the $\tan\beta$-enhanced Yukawa coupling).
Even in a model such as CMSSM with only a few New Physics parameters, both constraints
are required to effectively bound the parameter space.

electroweak constraints, while the blue (darker) contour makes the same
assumptions about the assumed LHC discoveries, but does not include any
external constraints.}

A working group on the ``Interplay between high-$p_T$ and flavor physics''
has been set up~\cite{interplay1}; the first meeting was held at CERN in December 2007~\cite{interplay2}.
