Constraint on K Kbar compositeness of the a0(980) and f0(980) resonances from their mixing intensity
, 2015 Structure of the $a_{0}(980)$ and $f_{0}(980)$ resonances is investigated with the $a_{0}(980)$-$f_{0}(980)$ mixing intensity from the viewpoint of compositeness, which corresponds to the amount of two-body states composing resonances as well as bound ...

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 ...

Modelling vector-like quarks in partial compositeness framework
Journal of High Energy Physics, 2022 Composite Higgs models, together with partial compositeness, predict the existence of new scalars and vector-like quarks (partners) at and above the TeV scale.

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.

Top Quark Condensate Revisited [PDF]
, 1996 In the light of recent discovery of a very heavy top quark, we reexamine the top quark condensate model proposed by Miransky, Tanabashi and Yamawaki (MTY) and by Nambu.

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 ...

Pole structure and compositeness
, 2017 We present in this talk a series of new results on the nature of a bound state or resonance based on the calculation of the expectation values of the number operators of the free particles in the state of interest.

Softly Broken Supersymmetric Gauge-Higgs-Yukawa Theories as Renormalizable Composite Models [PDF]
, 2000 We examine the (softly broken) supersymmetric gauge-Higgs-Yukawa theories satisfying the compositeness conditions at a certain scale. In these theories the Higgs superfields can be regarded as the chiral composite fields.

Constraints on spin-3/2 and excited spin-1/2 fermions coming from the leptonic Z0-partial width [PDF]
, 1993 We consider effective interactions among excited spin-1/2 and spin-3/2 leptons with the usual ones. Assuming that these new leptons are lighter than the Z0 we will study the constraints on their masses and compositeness scale coming from the leptonic Z0 ...
