Long-lived, colour-triplet scalars are a generic prediction of unnatural, or split, composite Higgs models where the spontaneous global-symmetry breaking scale f > 10 TeV and an unbroken SU(5) symmetry is preserved. Since the triplet scalars are pseudo Nambu-Goldstone bosons they are split from the much heavier composite-sector resonances and are the lightest exotic, coloured states. This...

The Standard Model suffers from many theoretical problems. What is the physical origin of the Electroweak symmetry breaking ? Why is the Higgs boson the only fundamental scalar in the Standard Model? As a consequence, why is there such a fine tuning in the Higgs sector ? And finally, where is Dark Matter ? Composite Higgs models can give answers to these questions in an appealing way. In these...

In the context of the minimal SO(5) linear {\sigma}-model, a complete renormalizable Lagrangian -including gauge bosons and fermions- is considered, with the symmetry softly broken to SO(4). The scalar sector describes both the electroweak Higgs doublet and the singlet {\sigma}. We analyze the phenomenological implications and constraints from precision observables and LHC data....

We provide a non-linear realisation of composite Higgs model in the context of $SU(4)_0 \times SU(4)_1/ Sp(4)$ symmetry breaking pattern, where the effective Lagrangian of the spin-0 and spin-1 resonances in this model is constructed via the CCWZ prescription. We investigate the EWPT constraint in this model by accounting the effects from reduced Higgs couplings and integrating out heavy...

The effective Lagrangian expansion provides a model independent framework to study effects of new physics at the electroweak scale. To make full use of LHC data in constraining higher-dimensional operators we need to include both the Higgs and the electroweak gauge sector in the analysis. We first present a combined analysis of the relevant diboson production LHC results to set the strongest...
