This talk will review the status of what we know about the observed Higgs boson decaying to fermions, together with the search for Physics beyond the standard model in cases with fermions in the final state. The presentation will cover the couplings from the analyses of final states and initial states like production in association with top quark pairs or single top quarks.

Induced electroweak symmetry breaking is an alternative to the Standard Model mechanism for triggering the Higgs vev which can preserve a Standard-Model-like Higgs decoupled from additional states. In composite Higgs models, this provides a natural mechanism to explain a hierarchy $v \ll f$ between the EWSB scale and the global symmetry breaking scale. In particular, we describe how composite...

ATLAS and CMS observe deviations from the expected background in the diphoton invariant mass searches of new resonances around 750 GeV. We show that a simple realization in terms of a new pseudoscalar state can accommodate the observations. The model leads to further footprints that can be soon observed. The new state can be interpreted both as an axion or as a highly natural composite state...

Towards the end of Run-1 data taking, an excess in the diboson as well as eejj channel was announced. During the first round of Run-2 data taking, an excess in diphoton channel has been announced. I consider possible explanations of these excesses in two different BSM scenarios. I demonstrate the feasibility of accommodating the diboson and eejj excess in a Left-Right Symmetric Standard Model....

The Large Hadron Collider has restarted pp collisions at 13 TeV center of mass energy in June 2015. The CMS experiments have taken data at this new energy which allows greater reach in probing for physics beyond the Standard Model. Several results on searches for physics not associated with supersymmetric extensions of the Standard Model are presented. To give few examples, these extensions...

The CMS SUSY program is very active in performing searches with the 13 TeV data including multiple analyses done in regions with leptonic final states. The results of these analyses are used to expand the reach of the searches done by CMS at 8 TeV and additionally to investigate two excesses seen in run I, namely a 2.6 sigma excess seen by CMS and a 3.0 sigma excess seen by ATLAS. These...

Many extensions of the Standard Model of particle physics predict heavy new particles and new phenomena, leading to characteristic signatures such as a narrow peak or excess in the tail of distributions. This talk highlights results on searches with fermionic signatures, mainly with high-pT jets and leptons, using 2015 data collected at 13 TeV.

Significant increase of the center-of-mass energy from 8 to 13 TeV at LHC Run II offers a great discovery potential for new physics at high mass, especially for strongly produced high-mass resources, contact interactions and TeV-gravity phenomena with high-pT jets. This talk presents most recent Run II results from ATLAS on new physics searches in the jet final states.

Direct searches for fermion and vector boson resonances, as well as indirect constraints from precision measurements are both important tools to test the predictions of composite Higgs models.

Signatures of large missing transverse momentum recoiling against jets at the LHC provide powerful probe to strongly produced dark matter (DM), complementary to direct and indirect DM detection experiments.

Recent anomalies in B meson decays observed by the LHCb collaboration have motivated the construction of extensions of the Standard Model with a gauged family non-universal U(1) factor.

I will discuss then phenomenological...

Updating various theoretical and experimental constraints on the four different types of two-Higgs-doublet models (2HDMs), we find that only the ``lepton-specific" (or ``type X") 2HDM can explain the present muon g−2 anomaly in the parameter region of large tanβ, a light CP-odd boson, and heavier CP-even and charged bosons which are almost degenerate. The severe constraints on the models come...

The analysis of the full LHC Run I data set of proton-proton collision events collected with the LHCb detector, corresponding to an integrated luminosity of 3.0 fb-1, is yielding several improved results on exotic hadron candidates, such as $X(3872)$ and $Z(4430)^+$, as well as the first observation of two new states compatible with the pentaquark hypothesis. Run II data allow LHCb to further...

The Belle II experiment at the SuperKEKB collider is a major upgrade of the KEK B factory in Tsukuba, Japan. The machine is designed for an instantaneous luminosity of $8\times 10^{35}$ cm$^{-2}$s$^{-1}$ and the experiment is expected to accumulate a data sample of about 50 ab$^{-1}$ in 5 years running. With this amount of data, decays sensitive to physics beyond the Standard Model can be...

By using the very first proton-proton collision data of the LHC Run II, LHCb performed a series of measurements, notably including the cross-sections for quarkonia, beauty and charm productions. The results have been carried out by exploiting a new scheme for the LHCb software trigger, where the algorithm has been split in two stages to allowing for a delayed trigger decision. This enables the...

Vetoing undesired jets is essential in many analyses aiming at searches for new particles. A new jet function, called N-jettiness has been introduced with the purpose of using an inclusive event shape variable for vetoing jets. The logarithms from the phase space restriction, are simple enough to allow their systematic summation to all orders, which allows for providing high precision...

The experimental data point towards the fact that the Standard Model, when assumed to be valid up to very high energies, might be metastable. The stability properties of the theory strongly depend on the Higgs and top masses, so that it becomes important to perform precise, unambiguous computations. Traditionally, these rely on calculating the effective potential and checking for an...
