“…The group-theoretical approach based on reduced matrix elements [245,744,745] is equivalent to a diagrammatic approach of topological amplitudes [746][747][748][749][750]. In the latter, it is easier to introduce dynamical assumptions such as neglecting annihilation-like amplitudes.…”

With the advent of the LHC, we will be able to probe New Physics (NP) up to energy scales almost one order of magnitude larger than it has been possible with present accelerator facilities. While direct detection of new particles will be the main avenue to establish the presence of NP at the LHC, indirect searches will provide precious complementary information, since most probably it will not be possible to measure the full spectrum of new particles and their couplings through direct production. In particular, precision measurements and computations in the realm of flavor physics are expected to play a key role in constraining the unknown parameters of the Lagrangian of any NP model emerging from direct searches at the LHC.The aim of Working Group 2 was twofold: on the one hand, to provide a coherent up-to-date picture of the status of flavor physics before the start of the LHC; on the other hand, to initiate activities on the path towards integrating information on NP from high-p T and flavor data.This report is organized as follows: in Sect. 1, we give an overview of NP models, focusing on a few examples that have been discussed in some detail during the workshop, with a short description of the available computational tools for flavor observables in NP models. Section 2 contains a concise discussion of the main theoretical problem in flavor physics: the evaluation of the relevant hadronic matrix elements for weak decays. Section 3 contains a detailed discussion of NP effects in a set of flavor observables that we identified as "benchmark channels" for NP searches. The experimental prospects for flavor physics at future facilities are discussed in Sect. 4. Finally, Sect. 5 contains some assessEur. Phys. J. C (2008) 57: 309-492 311 ments on the work done at the workshop and the prospects for future developments.

“…In [9], we use the quark diagram or the so-called topological approach, which was proposed in and has been used extensively in mesonic modes [28][29][30][31][32] (for a recent review, see [16]), to the charmless two-body baryonic decays and obtained predictions on relative rates. In fact, the same approach was also applied to charmful baryonic B 0 → Λ + c p decay [27].…”

We study charmless two-body baryonic B decays using the topological amplitude approach.We extend a previous work to include all ground state octet and decuplet final states with full topological amplitudes. Relations on rates and CP asymmetries are obtained. The number of independent topological amplitudes is significantly reduced in the large m B asymptotic limit. With the long awaited B 0 → pp data, we can finally extract information on the topological amplitudes and predict rates of all other modes. The predicted rates are in general with uncertainties of a factor of two by including corrections to the asymptotic relations and from sub-leading contributions. We point out some modes that will cascadely decay to all charged final states and have large decay up "subleading contributions", which will affect other modes including the B 0 → pp decay. We need more data to clarify the situation. The analysis presented in this work can be systematically improved when more measurements on decay rates become available.

“…Thus it is hard to make any definite conclusion of signals of new physics. This is also true in most of the channels like b → sqq [4] and b → sll [5], due to the theoretical uncertainties.…”

For any new physics possibly emerging in the future B experiments, the problem is how to extract the signals from the SM background. We consider the decay b → ssd which is very small in the SM. In the MSSM this decay is possibly accessible in the future experiments. In the supersymmetric models with R-parity violating couplings, this channel is not strictly constrained, thus being useful in obtaining bounds on the lepton-number violating couplings. A typical candidate for the suggested search is the12.15.Ji, 13.25.Hw, 12.60.Jv 1 Alexander von Humboldt research fellow.
