Phenomenology of unusual top partners in composite Higgs models

open access: yesJournal of High Energy Physics, 2022
We consider a particular composite Higgs model which contains SU(3) color octet top partners besides the usually considered triplet representations. Moreover, color singlet top partners are present as well which can in principle serve as dark matter ...

Surfel Set Simplification With Optimized Feature Preservation

open access: yesIEEE Access, 2016
In this paper, we propose a novel scheme for simplifying a surfel set with the resultant surfels computed and distributed to preserve prominent geometric and textural features. It works by iteratively collapsing local neighborhoods around surfels until a

3D Rigid Registration of Intraoperative Ultrasound and Preoperative MR Brain Images Based on Hyperechogenic Structures

open access: yesInternational Journal of Biomedical Imaging, 2012
The registration of intraoperative ultrasound (US) images with preoperative magnetic resonance (MR) images is a challenging problem due to the difference of information contained in each image modality. To overcome this difficulty, we introduce a new

The Linear BESS model at the LHC

open access: yesNuclear Physics B, 2018
In this work we consider the Linear BESS model at the LHC. This model can be seen as an adequated benchmark for exploring the phenomenological consequences of a composite Higgs sector since its particle content is the one we would expect in a realistic ...

Search for new resonances in Wγ and Zγ final states in pp collisions at s=8 TeV with the ATLAS detector

open access: yesPhysics Letters B, 2014
This Letter presents a search for new resonances decaying to final states with a vector boson produced in association with a high transverse momentum photon, Vγ, with V=W(→ℓν) or Z(→ℓ+ℓ−), where ℓ=e or μ.

Composite Higgs at high transverse momentum

open access: yesJournal of High Energy Physics, 2020
In this paper we explore composite Higgs scenarios through the effects of light top-partners in Higgs+Jet production at the LHC. The pseudo-Goldstone boson nature of the Higgs field means that single-Higgs production via gluon fusion is insensitive to ...

Extended technicolor models with two extended technicolor groups [PDF]

open access: yesPhysical Review D, 2006
We construct extended technicolor (ETC) models that can produce the large splitting between the masses of the $t$ and $b$ quarks without necessarily excessive contributions to the $\rho$ parameter or to neutral flavor-changing processes. These models make use of two different ETC gauge groups, such that left- and right-handed components of charge $Q=2 ...

Phenomenology of flavorful composite vector bosons in light of B anomalies

open access: yesJournal of High Energy Physics, 2017
We analyze the flavor structure of composite vector bosons arising in a model of vectorlike technicolor — often called hypercolor (HC) — with eight flavors that form a one-family content of HC fermions.

Is the Higgs mechanism of fermion mass generation a fact? A Yukawa-less first-two-generation model

open access: yesPhysics Letters B, 2016
It is now established that the major source of electroweak symmetry breaking (EWSB) is due to the observed Higgs particle. However, whether the Higgs mechanism is responsible for the generation of all the fermion masses, in particular, the fermions of ...
