Explaining the t-tbar asymmetry with a light axigluon

, 2011
We propose an axigluon with mass between 400 and 450 GeV and flavor universal couplings to quarks to explain the Tevatron t-tbar forward-backward asymmetry.

Higher Dimensional Effective Operators for Direct Dark Matter Detection

, 2014
We discuss higher dimensional effective operators describing interactions between fermionic dark matter and Standard Model particles. They are typically suppressed compared to the leading order effective operators, which can explain why no conclusive ...

Next-to-Next-to-Leading-Order Charm-Quark Contribution to the CP Violation Parameter epsilon_K and Delta M_K

, 2012
The observables epsilon_K and Delta M_K play a prominent role in particle physics due to their sensitivity to new physics at short distances. To take advantage of this potential, a firm theoretical prediction of the standard-model background is essential.

Top quark forward-backward asymmetry in R-parity violating supersymmetry

, 2012
The interaction of bottom squark-mediated top quark pair production, occurring in the R-parity violating minimal supersymmetric standard model (MSSM), is proposed as an explanation of the anomalously large $t\bar{t}$ forward-backward asymmetry (FBA ...

A formal introduction to Horndeski and Galileon theories and their generalizations

, 2013
We review different constructions of Galileon theories in both flat and curved space, and for both single scalar field models as well as multi-field models.

Higgs searches and singlet scalar dark matter: Combined constraints from XENON 100 and the LHC

, 2011
XENON100 and the LHC are two of the most promising machines to test the physics beyond the Standard Model. In the meantime, indirect hints push us to believe that the dark matter and Higgs boson could be the two next fundamental particles to be ...

Where Economics Has Been Headed? Multiple Identities And Diversity In Economic Literature Evidence From Top Journals Over The Period 2000-2006 A First Note [PDF]

This short paper presents some preliminary results of an ongoing research work focusing on richness and diversity of economic literature. The key idea is that each article published in an economic journal retains multiple identities.
