The lepton mixing angle theta 13, the only unknown angle in the standard three-flavor neutrino mixing scheme, is finally measured by recent reactor and accelerator experiments. We perform a combined analysis of the data coming from T2K, MINOS , Double Chooz, and Daya Bay, extracting a 6.2 sigma significance for nonzero theta 13. We also discuss near future expectations on the precision of the...

Lattice QCD benefits nowadays from numerous progess thanks to algorithmic enhancements to push down the quark masses to reach the physical masses and to increase the lattice geometry to avoid finite volume effects. However using fermions which do not break the chiral symmetry both in valence and sea sector is still a challenge. An alternative is to consider mixed action simulations, where one...

The BMSSM (Beyond the MSSM) framework is an effective theory approach that encapsulates a variety of extensions beyond the MSSM with which it shares the same field content. The lightest Higgs mass can be much heavier than in the MSSM without creating a tension with naturalness or requiring superheavy stops. The phenomenology of the Higgs sector is at the same time much richer. I discuss here...

I will (extremely) briefly review the evidence for dark matter and then the ongoing efforts to detect it using indirect and direct detection. I will talk about recent developments in indirect detection including a couple of potential signals from Fermi and some recent pessimistic predictions from N-body simulations. I will then review the ongoing search for dark matter via direct detection. ...

The relic density of Dark Matter in the Universe imposes today one of the most stringent constraints on new physics models such as the Minimal Supersymmetric Standard Model (MSSM). The most recent analysis of the WMAP collaboration has already reached an accuracy of 3%, and the upcoming results obtained with the Planck satellite will be even more precise. It is therefore mandatory for the...

In this talk I will present a study on the NUHM2 supersymmetric model where both the cosmic inflation and the observed dark matter abundance can be explained, with a Higgs boson mass in the range favoured by the latest LHC data. The two inflaton candidates
LLe and udd are embedded within the MSSM therefore their decay naturally excites all the relevant degrees of freedom which thermalizes the...

I will describe how neutrinos could go faster than the speed of light in a dense environment if gravity were modified by a scalar field. I will show that the speed difference would almost always be unobservable for natural values of the couplings of scalars to matter.

The inverse seesaw is a very appealing mechanism to generate neutrino masses since it provides natural neutrino Yukawa couplings ($Y_\nu \sim O(1)$) and a seesaw scale close to the electroweak one, thus within LHC reach.
In a previous work (arXiv:1111.5836) where we embedded the inverse seesaw in a supersymmetric extension of the Standard Model (MSSM), we have highlighted that the...

We study the perturbative evolution of a jet via multiple gluon emissions induced by the interactions between the jet constituents and a dense QCD medium like a quark-gluon plasma. We focus on the typical medium-induced gluon emissions, for which the gluon formation time is much smaller than the overall size of the medium. We show that the typical time between two subsequent emissions is...

Baryon (B) and lepton (L) numbers are conserved in the standard model lagrangian, but generally not in new physics models. In this talk, we adopt an effective approach to analyze, in a model-independent way, the possible signatures of B and L violating interactions at the LHC. Then, we particularize the discussion to the minimal supersymmetric standard model, where such interactions may now be...

We discuss the advantages of combining the experimental bound on B(Bs->mu+ mu-) and the measured B(B->Kl+l-) to get the model independent constraints on physics beyond the Standard Model. Since the two decays give complementary information, one can study not only the absolute values of the Wilson coefficients that are zero in the Standard Model, but also their phases. We also emphasize the...

With the help of the Mellin-Barnes transform, we show how to simultaneously resum the expansion of any kind of non-analytic functions around 0, 1 and $ infinity$ in a systematic way. We exemplify the method for the perturbative vector, axial scalar and pseudo-scalar correlator at $\mathcal{O}(\alpha_s^{3})$. We show that the coefficients, $\Omega(n)$, of the Taylor expansion of the vacuum...
