On the intrinsic limitation of the Rosenbluth method at large momentum transfer

E. Tomasi-Gustafsson

Correlations in the elastic electron proton scattering data show that the Rosenbluth method is not reliable for the extraction of the electric proton form factors at large momentum…

Baryon spectra with instanton induced forces

B. Silvestre-Brac, F. Brau, C. Semay

Except the vibrational excitations of $K$ and $K^{*}$ mesons, the main features of spectra of mesons composed of quarks $u$ , $d$ , and $s$ can be quite well described by a semirelativ…

An angular distribution analysis of $Λ_{b}$ decays

O. Leitner, Z. J. Ajaltouni, E. Conte

A study of the angular distributions of the processes $Λ_{b} \to Λ V (1^{-})$ with $V (J /Ψ, ρ^{0})$ is performed. Emphasis is put on the initial $Λ_{b}$ polarization and the polarization d…

$Λ_{b}$ Decays into $Λ$ -Vector

Z. J. Ajaltouni, E. Conte, O. Leitner

A complete study of the angular distributions of the processes, $Λ_{b} \to Λ V (1^{-})$ , with $Λ \to p π^{-}$ and $V (J /Ψ) \to ℓ^{+} ℓ^{-}$ or $V (ρ^{0}, ω) \to π^{+} π^{-},$ is performed.…

Mass and decays of Brout-Englert-Higgs scalar with extra generations

J. -M. Frere, A. N. Rozanov, M. I. Vysotsky

The higher bound on the mass of the Brout-Englert-Higgs scalar boson (BEH boson for brevity) arising from radiative corrections is not stable when the Standard Model is extended to…

Virtual Compton Scattering at Low Energy and the Generalized Polarizabilities of the Nucleon o

H. Fonvieille

Virtual Compton Scattering on the nucleon: $γ^{*} N \to γ N$ is a new and rapidly developing field at low and high energies. This lecture is about the low energy part, i.e. for energi…
