New-physics contributions to the forward-backward asymmetry in B -> K* mu+ mu-

Ashutosh Kumar Alok, Amol Dighe, Diptimoy Ghosh +4

We study the forward-backward asymmetry (AFB) and the differential branching ratio (DBR) in B -> K* mu+ mu- in the presence of new physics (NP) with different Lorentz structures. W…

New Physics in Bs -> J/psi phi: a General Analysis

Cheng-Wei Chiang, Alakabha Datta, Murugeswaran Duraisamy +3

Recently, the CDF and D0 collaborations measured indirect CP violation in Bs -> J/psi phi and found a hint of a signal. If taken at face value, this can be interpreted as a nonzero…

From the LHC to Future Colliders

A. De Roeck, J. Ellis, C. Grojean +61

Discoveries at the LHC will soon set the physics agenda for future colliders. This report of a CERN Theory Institute includes the summaries of Working Groups that reviewed the phys…

Vertex Displacements for Acausal Particles: Testing the Lee-Wick Standard Model at the LHC

Ezequiel Alvarez, Leandro Da Rold, Carlos Schat +1

We propose to search for wrong displaced vertices, where decay products of the secondary vertex move towards the primary vertex instead of away from it, as a signature for microsco…

CP Violation in Three-Body Chargino Decays

Makiko Nagashima, Ken Kiers, Alejandro Szynkman +3

CP violation in supersymmetry can give rise to rate asymmetries in the decays of supersymmetric particles. In this work we compute the rate asymmetries for the three-body chargino…

Diagnostic for new physics in decays

Seungwon Baek, Cheng-Wei Chiang, Michael Gronau +2

A recent analysis of decays concludes that present data do not clearly indicate whether (i) the standard model (or new physics) is sufficient, or (ii) new…

Looking for New Physics in B --> K^* πand B --> ρK Decays

Cheng-Wei Chiang, David London

B --> K^* πand B --> ρK decays involve the same quark-level processes as B --> πK. Analyzing the measurements of the former decays might be able to shed additional light on the new…

The B -> pi K Puzzle: 2009 Update

Seungwon Baek, Cheng-Wei Chiang, David London

The measurements of B -> pi K decays have been in disagreement with the predictions of the Standard Model (SM) for some time. In this paper, we perform an update of this puzzle usi…

One Universal Extra Dimension in Pythia

M. ElKacimi, D. Goujdami, H. Przysiezniak +1

The Universal Extra Dimensions model has been implemented in the Pythia generator from version 6.4.18 onwards, in its minimal formulation with one inverse-TeV-sized extra dimension…
