The B -> pi K Puzzle and New Physics
Seungwon Baek, Philippe Hamel, David London +2
The present B -> pi K data is studied in the context of the standard model (SM) and with new physics (NP). We confirm that the SM has difficulties explaining the B -> pi K measurem…
A Measurement of gamma from the Decays Bd(t) -> D(*)+ D(*)- and Bd -> Ds(*)+ D(*)-
Justin Albert, Alakabha Datta, David London
Recently, it was proposed to use measurements of Bd(t) -> D(*)+ D(*)- and Bd -> Ds(*)+ D(*)- decays to measure the CP phase gamma. In this paper, we present the extraction of gamma…
Bd^0(t)->pi^+pi^- and Bs^0(t)-> K^+ K^- Decays: A Tool to Measure New-Physics Parameters
David London, Joaquim Matias, Javier Virto
If physics beyond the standard model is present in B decays, experimental measurements seem to suggest that it principally affects those processes with significant b->s penguin amp…
CP Violation in B -> pi K Decays
Maxime Imbeault
I briefly review CP violation in the B system, concentrating on B -> pi K decays. I discuss how to deal with electroweak-penguin contributions to these decays using flavour SU(3).…
New Physics Signals through CP Violation in B -> rho,pi
Veronique Page
We describe here a method for detecting physics beyond the standard model via CP violation in B->rho,pi decays. Using a Dalitz-plot analysis to obtain alpha, along with an analytic…
Methods for Measuring New-Physics Parameters in B Decays
Alakabha Datta, Maxime Imbeault, David London +3
Recently, it was argued that new-physics (NP) effects in B decays can be approximately parametrized in terms of a few quantities. As a result, CP violation in the system allows…
CP Violation in the B System: Measuring New-Physics Parameters
David London
I review CP violation in the standard model (SM). I also describe the predictions for CP violation in the B system, along with signals for physics beyond the SM. I stress the numer…
Measuring New-Physics Parameters in B Penguin Decays
Alakabha Datta, David London
We examine new-physics (NP) effects in B decays with large b -> s penguin amplitudes. Decays involving b -> d penguins are assumed to be unaffected. We consider a model-independent…
Testing the Standard Model with Bs-> K^+ K^- Decays
David London, Joaquim Matias
In the limit of flavor SU(3) symmetry, the amplitudes for Bd->pi^+π^- and Bs-> K^+ K^- are related to one another. Taking the values of the weak phases beta and gamma from independ…
Obtaining CKM Phase Information from B Penguin Decays
Alakabha Datta, David London
We discuss a method for extracting CP phases from pairs of B decays which are related by flavor SU(3). One decay (B0 -> M1 M2) receives a significant bbar -> dbar penguin contribut…
Dynamical CP Violation in the Early Universe
K. R. S. Balaji, Tirthabir Biswas, Robert H. Brandenberger +1
Following earlier ideas of Dolgov, we show that the asymmetrical dynamical evolution of fields in the early Universe provides a new source for CP violation. This can lead to baryog…
Prospects for the Search for a Standard Model Higgs Boson in ATLAS using Vector Boson Fusion
S. Asai, G. Azuelos, C. Buttar +14
The potential for the discovery of a Standard Model Higgs boson in the mass range m_H < 2 m_Z in the vector boson fusion mode has been studied for the ATLAS experiment at the LHC.…
Bounds on New Physics from B -> V1 V2 Decays
David London, Nita Sinha, Rahul Sinha
We consider the possibility that physics beyond the standard model contributes to the decays B -> V1 V2, where V1 and V2 are vector mesons. We show that a time-dependent angular an…
Exploring Little Higgs Models with ATLAS at the LHC
G. Azuelos, K. Benslama, D. Costanzo +8
We discuss possible searches for the new particles predicted by Little Higgs Models at the LHC. By using a simulation of the ATLAS detector, we demonstrate how the predicted quark,…
Phenomenological Constraints on Extra-Dimensional Scalars
G. Azuelos, P. -H. Beauchemin, C. P. Burgess
We examine whether the ATLAS detector has sensitivity to extra-dimensional scalars (as opposed to components of higher-dimensional tensors which look like 4D scalars), in scenarios…
Production of Excited Neutrino at LHC
A. Belyaev, C. Leroy, R. Mehdiyev
We study the potential of the CERN LHC in the search for the single production of excited neutrino through gauge interactions. Subsequent decays of excited neutrino via gauge inter…
Signals from R-parity violating top quark decays at LHC
A. Belyaev, M-H. Genest, C. Leroy +1
We evaluate the potential of the CERN LHC collider to observe rare decays of the top quark in channels involving R-parity violating (RPV) interactions. We stress the importance of…
