The W boson mass weighs in on the non-standard Higgs
Physics Letters B, 2022 We consider the implications of the CDF collaboration high-precision measurement of the W boson mass on models with a non-standard Higgs. We show that this requires an enhancement of more than 5% in the non-standard Higgs coupling to the gauge bosons ...

Electroweak symmetry breaking and collider signatures in the next-to-minimal composite Higgs model
Journal of High Energy Physics, 2017 We conduct a detailed numerical analysis of the composite pseudo-Nambu-Goldstone Higgs model based on the next-to-minimal coset SO(6)/SO(5) ≅ SU(4)/Sp(4), featuring an additional SM singlet scalar in the spectrum, which we allow to mix with the Higgs ...

iTIMP: isotriplet Technicolor Interacting Massive Particle as Dark Matter [PDF]
, 2009 We suggest that a weak isotriplet composite scalar possessing an unbroken U(1) global symmetry naturally arises in technicolor models leading to an interesting type of dark matter candidate: the iTIMP. We propose explicit models of the iTIMP, study earth

The LHC potential of vector-like quark doublets
Journal of High Energy Physics, 2018 The existence of new vector-like quarks is often predicted by models of new physics beyond the Standard Model, and the development of discovery strategies at colliders is the object of an intense effort from the high-energy community.

Effective theories of dark mesons with custodial symmetry
Journal of High Energy Physics, 2019 Dark mesons are bosonic composites of a new, strongly-coupled sector beyond the Standard Model. We consider several dark sectors with fermions that transform under the electroweak group, as arise from a variety of models including strongly-coupled ...

Collider tests of the Renormalizable Coloron Model
Journal of High Energy Physics, 2018 The coloron, a massive version of the gluon present in gauge extensions of QCD, has been searched for at the LHC as a dijet or top quark pair resonance.

Gravitation waves from QCD and electroweak phase transitions
Journal of High Energy Physics, 2018 We investigate the gravitation waves produced from QCD and electroweak phase transitions in the early universe by using a 5-dimension holographic QCD model and a holographic technicolor model.
