Astrophysical bound on the majoron-Higgs-boson coupling
1989
Abstract We show that the coupling of the “standard” Higgs boson to majorons, that could lead to a very fast decay of the neutral Higgs scalar to invisible modes, can be bounded using astrophysical arguments. We discuss the relevance of this bound for low-energy phenomenology related to majoron production. The bound so obtained may also jeopardize the stability of the VEV hierarchy in the doublet and triplet majoron models if the mass of the top quark is less than the W mass. A similar analysis may be applied to other models which exhibit Goldstone-or pseudo-Goldstone-bosons in the spectrum.

Étude de l’attractivité et de la fidélisation auprès d’établissements d’accueil de personnes âgées de deux bassins territoriaux
2015
International audience; Actuellement le marché du travail des jeunes subit encore l’instabilité de la conjoncture économique et sociale née à partir du milieu des années soixante dix, à la fin de la période des « trente glorieuses ». Ce marché est également paradoxal car, malgré un taux de chômage élevé de la population des jeunes actifs, certains secteurs d’activité, ne parviennent ni à embaucher, ni à fidéliser leur personnel. Cette communication présente une analyse des mesures prises par des organisations pour attirer et fidéliser une main d’œuvre jeune et pour la faire progresser dans un contexte de précarisation des parcours professionnels qui impacte les pratiques de fidélisation dép…
Virtual and Augmented Reality in Finance: State Visibility of Events and Risk"
2021
This chapter reflected on the potential of Virtual Reality and Augmented Reality (VR / AR) technologies in supporting the dynamics of global financial systems and in addressing the grand challenges posed by unexpected events and crisis. The chapter briefly overviewed traditional VR/AR uses and described three early attempts to use 3D/ VR / AR technologies in Finance. In light of the recent financial crisis, there is a potential added valued in harnessing the use of VR/AR technologies to convey a greater visibility of the financial state (including visibility of financial risk). Various dimensions of the problem are considered. The chapter suggested a blend of service oriented computing SOC …

ɛ-type contribution to baryon asymmetry from colored Higgs triplets
1991
In scenarios where the cosmological baryon asymmetry is generated in the decay of heavy colored Higgs triplets at the one-loop level (at least two triplets are needed), it is shown that in addition to the conventional triangle loop ({epsilon}{prime}-type effect), a new kind of diagram must be considered. This new type of diagram has its origin in the mixing of the two Higgs fields ({epsilon}-type effect). The mixing of the two Higgs fields violates {ital CP} provided they have at least two common decay channels. For small mixing angles, the new contribution can be bigger than the conventional one.
Ladri di luce. Leonardo Sciascia e Piero Guccione tra bellezza e verità
2023
The unpublished correspondence between Leonardo Sciascia and Piero Guccione from 1975 to 1989 shows the profound charge of humanity that innervates the friendship between these two great Enlightenment leaders "upside down". A "correspondence of amorous senses", despite the inevitable ideological differences, which the letters reproduced here for the first time and the original contributions of the volume give us back, under the banner of the binomial "beauty-truth".
From a "child of light" to a "woman of genius": Sarah Grand's the beth book as the new woman bildungsroman
2021
The New Woman fiction, popular in the last decade of the 19th century, contested the traditional notions of gender roles and participated in the public debates on women’s rights. The protagonists of the New Woman novels refused to conform to the submissive and self-abnegating Victorian ideal of femininity. The article discusses the ways in which Sarah Grand, a prominent New Woman novelist and social activist, uses and transforms both the elements of her own life and the Bildungsroman conventions in her 1897 novel The Beth Book to create a heroine whose growth and development result in her personal independence and her active public engagement in women’s issues. Cast in a variety of social r…
Critical end point behaviour in a binary fluid mixture
1997
We consider the liquid-gas phase boundary in a binary fluid mixture near its critical end point. Using general scaling arguments we show that the diameter of the liquid-gas coexistence curve exhibits singular behaviour as the critical end point is approached. This prediction is tested by means of extensive Monte-Carlo simulations of a symmetrical Lennard-Jones binary mixture within the grand canonical ensemble. The simulation results show clear evidence for the proposed singularity, as well as confirming a previously predicted singularity in the coexistence chemical potential [Fisher and Upton, Phys. Rev. Lett. 65, 2402 (1990)]. The results suggest that the observed singularities, particula…
