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 ...

Strong Conformal Dynamics at the LHC and on the Lattice

open access: yes, 2009
Conformal technicolor is a paradigm for new physics at LHC that may solve the problems of strong electroweak symmetry breaking for quark masses and precision electroweak data.

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 ...

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.

Technicolor [PDF]

open access: yes, 1996
Technicolor, with extended technicolor, is the theory of dynamical electroweak and flavor symmetry breaking at energies far below the Planck scale. To motivate it, I describe the most important difficulties of the standard electroweak model of symmetry

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 ...

Conformal Technicolor

open access: yes, 2006
We point out that the flavor problem in theories with dynamical electroweak symmetry breaking can be effectively decoupled if the physics above the TeV scale is strongly conformal, and the electroweak order parameter has a scaling dimension d = 1 ...

Mnemozid auf Shutter Island (2010)

open access: yesÖsterreichische Zeitschrift für Geschichtswissenschaften, 2013
“You gotta make a choice ... If you wanna uncover the truth ... you have to let her go!” – With these lines, spoken by a madman at Ash­ cliffe Hospital on Shutter Island who is expecting the night of enlightenment: the lobotomy in the lighthouse ...
