Electroweak Symmetry Breaking by Strong Dynamics and the Collider Phenomenology [PDF]
, 2002 We discuss the possible signatures in the electroweak symmetry breaking sector by new strong dynamics at future hadron colliders such as the Tevatron upgrade, the LHC and VLHC, and $e^+e^-$ linear colliders.

Generalized weak-binding relations of compositeness in effective field theory [PDF]
, 2016 We study the compositeness of near-threshold states to investigate the internal structure of exotic hadron candidates. Within the framework of effective field theory, Weinberg's weak-binding relation is extended to more general cases by easing several ...

European Physical Journal C: Particles and Fields, 2019 We present a non-perturbative lattice study of $$\mathrm {SU}(4)$$ SU(4) gauge theory with two flavors of fermions in the fundamental representation and two in the two-index antisymmetric representation: a theory closely related to a minimal partial ...

Transatlantica, 2013 Il s’agit de s’interroger sur ce qui se joue dans l’écriture littéraire et sur ce qui explique la difficulté qu’ont les non littéraires à saisir le travail de la langue et la composition esthétique de l’œuvre, lesquels assurent la puissance cognitive du texte littéraire et le distinguent fondamentalement des autres objets de fiction auquel il est ...

Hadronic few-body systems in chiral dynamics, -- Few-body systems in hadron physics -- [PDF]
, 2012 Hadronic composite states are introduced as few-body systems in hadron physics. The $\Lambda(1405)$ resonance is a good example of the hadronic few-body systems.

Anatomy of the newly observed hidden-charm pentaquark states: Pc(4312), Pc(4440) and Pc(4457)
Physics Letters B, 2019 We study the newly reported hidden-charm pentaquark candidates Pc(4312), Pc(4440) and Pc(4457) from the LHCb Collaboration, in the framework of the effective-range expansion and resonance compositeness relations.

, 2011 We present a mechanism that naturally produces light Dirac neutrinos. The basic idea is that the right-handed neutrinos are composite. Any realistic composite model must involve `hidden flavor' chiral symmetries.

Testing a dynamical origin of Standard Model fermion masses [PDF]
, 2016 We discuss a test of the Standard Model fermion mass origin in models of dynamical electroweak symmetry breaking. The couplings of composite pseudoscalar resonances to top quarks allow to distinguish high-scale Extended-Technicolor-type fermion mass ...

Two-body wave functions and compositeness from scattering amplitudes: General properties with schematic models [PDF]
, 2016 For a general two-body bound state in quantum mechanics, both in the stable and decaying cases, we establish a way to extract its two-body wave function in momentum space from the scattering amplitude of the constituent two particles.

HERA prospects on Compositeness and New Vector Bosons [PDF]
, 1996 The absence of deviations from the Standard Model for the differential cross section ${d\sigma}/{dQ^2}$ at HERA is used to set limits on electron quark compositeness scale and on new vector bosons, especially the hadrophilic one recently introduced as a ...
