The LHCb detector is a forward single arm spectrometer designed primarily for the study of CP-violation and other rare phenomena in the decays of beauty and charm particles. LHCb is very powerful in probing New Physics by performing indirect searches. Nevertheless, a program of direct searches for Higgs and Higgs-like particles also exists. Here we present some recent results and perspectives.

After a brief introduction on the physical motivation for Composite Higgs models, I will discuss cosets leading to Composite Two Higgs Doublet Models. I will analyze in detail the problem of tree level custodial symmetry breaking and how this problem can be solved, as well as the specific embedding for fermion fields that allow to avoid Higgs mediated Flavor Changing Neutral Currents.

We propose a new mechanism to suppress the flavor changing neutral currents in a three-Higgs doublet extension of the standard electroweak model. This mechanism has three ingredients: i) The three SU(2) Higgs scalar doublets transform as the reducible representation triplet of the discrete S3 symmetry that breaks to the irreducible representations, a doublet and a singlet; ii) an appropriate...

The scalar particle recently discovered at the LHC has the same gauge quantum
numbers as the neutrino, so that one can ask if they can be one the superpartner of the
other. In this talk I will discuss such a possibility, discussing a model where
this is realised. This model has an interesting phenomenology at the LHC.

Since the discovery of a Higgs-like boson by the ATLAS and CMS experiments at the LHC, the emphasis has shifted towards measurements of its properties and the search for the search in the less sensitive channels in order to determine whether the new particle is the Standard Model (SM) Higgs boson. Of particular importance is the direct observation of the coupling of the Higgs boson to...

The spin and parity of the recently discovered Higgs boson using the ATLAS detector and up to 25 fb-1 of 7 TeV and 8 TeV pp collision data collected in 2011 and 2012, was probed in the diboson (γγ, WW and ZZ) channels. These results and their combinations are presented.

The recent discovery of a SM-like Higgs boson at the LHC, with a mass around 125-126 GeV, together with the absence of results in the direct searches for supersymmetry, is pushing the SUSY scale ($m_\text{SUSY}$) into the multi-TeV range. This discouraging situation from a low-energy SUSY point of view has its counterpart in indirect SUSY observables which present a non-decoupling behavior...

With the aim of linking natural supersymmetry to flavour physics, a model is proposed based on a family symmetry G × U(1), where G is a discrete nonabelian subgroup of SU(2), with both F-term and (abelian) D-term supersymmetry breaking. A good fit to the fermion masses and mixing is obtained with the same U(1) charges for the left- and right- handed quarks of the first two families and the...

We review and develop consistent treatments of theoretical uncertainty (TU) in Higgs couplings fits, going beyond the current approximation of uncorrelated Gaussian TU. We emphasize two different conceptual lines in the treatment of TU either as a nuisance or as a bias. These two treatments are considered within both frequentist and Bayesian frameworks. We develop the bias approach in the...

We present studies of multiple boson production in pp collisions at 7 TeV and 8 TeV center-of-mass energy based on data recorded by the CMS detector at the LHC in 2011 and 2012. These include precision cross section measurements and investigation of kinematic distributions. The results are interpreted in terms of constraints on anomalous triple and quartic gauge couplings, together with future...

After I presenting an analysis of the operators in supersoft SUSY breaking, I will discuss the requirements that must be satisfied by successful UV completions and the modifications of minimal supersoft mechanism needed to avoid negative mass squareds for adjoint scalars.
I will then present a complete model of dynamical supersymmetry breaking resulting in realistic superpartner spectrum with...
