Supersymmetric Contributions to Bs->K+K-

Seungwon Baek, David London, Joaquim Matias +1

Inspired by the existing calculation of B->piK decays in supersymmetry (SUSY), we evaluate the dominant SUSY contributions to Bs->K+K-. We show that the observables of this process…

Measurements of New Physics in B -> pi pi Decays

Seungwon Baek, F. J. Botella, David London +1

If new physics (NP) is present in B -> pi pi decays, it can affect the isospin I=2 or I=0 channels. In this paper, we discuss various methods for detecting and measuring this NP. T…

Polarization States in B -> rho K* and New Physics

Seungwon Baek, Alakabha Datta, Philippe Hamel +2

The standard-model explanations of the anomalously-large transverse polarization fraction fT in B -> phi K* can be tested by measuring the polarizations of the two decays B+ -> rho…

and the upward-going muon flux from the WIMP annihilation in the sun or the earth

Seungwon Baek, Yeong Gyun Kim, P. Ko

We consider the upward-going muon flux due to the WIMP annihilations in the cores of the sun and the earth, including the upper bound on the branching ratio for d…

Can one detect new physics in I=0 and/or I=2 contributions to the decays B --> pi pi?

Seungwon Baek, F. J. Botella, David London +1

We study the effects of new-physics contributions to B --> pi pi decays, which can be parametrized as four new complex quantities. A simple analysis is provided by utilizing the re…

Dynamical CP Violation in the Early Universe and Leptogenesis

K. R. S. Balaji, Tirthabir Biswas, Robert H. Brandenberger +1

In a recent publication, we suggested a mechanism for obtaining dynamical CP violation in the early Universe based on the out-of-equilibrium evolution of complex scalar fields. In…

Direct detection of neutralino dark matter in supergravity

S. Baek, D. G. Cerdeno, Y. G. Kim +2

The direct detection of neutralino dark matter is analysed in general supergravity scenarios, where non-universal soft scalar and gaugino masses can be present. In particular, the…

Prospects for the Search for a Doubly-Charged Higgs in the Left-Right Symmetric Model with ATLAS

G. Azuelos, K. Benslama, J. Ferland

We estimate the potential for observation at the LHC of a doubly charged Higgs boson, as predicted in Left-Right symmetric models. Single production by vector boson fusion, $W^+W^+…

Leptoquark Single and Pair production at LHC with CalcHEP/CompHEP in the complete model

Alexander Belyaev, Claude Leroy, Rashid Mehdiyev +1

We study combined leptoquark (LQ) single and pair production at LHC at the level of detector simulation. A set of kinematical cuts has been worked out to maximize significance for…
