We propose a new mechanism to generate baryons. Electroweak strings produced at the electroweak phase transition will introduce anomalous currents through interactions of the strings with the background electromagnetic field and through changes in the helicity of the string network. These anomalous currents will produce fluctuations in the baryon and lepton number. We show that in the two-Higgs...

Motivated by recent developments, we explore some issues in Affleck-Dine baryogenesis. We consider in greater detail the role of thermal effects in the production of baryon number. We find that these effects are important even for rather flat potentials, and obtain somewhat different estimates of the baryon asymmetry than those in the literature. We also consider the decay of the condensate, an...

The description of baryon resonance masses and decays in the constituent quark model is outlined, with emphasis on the potential-model approach combined with the P0 pair-creation model of strong decays. This approach allows the estimation of branching fractions for baryon states missing in πN elastic scattering analyses but expected to be present in electromagnetic production. Prospects for the...

Results are presented for the 500 GeV/c pion production asymmetry and polarization of the Λ c (Λ c) charmed baryon from Fermilab experiment E791. An analysis of the decay to the pKπ final state is described. Resonant sub-channel fractions and phases are given and possible resonant effects in the low mass pK system discussed. Significant decay to Λ c → ∆ ++ K − establishes for the first time the...

Particle production as observed with the BRAHMS experiment at RHIC is presented. Preliminary baryon/meson ratios and nuclear modification factors at different rapidities will be discussed.

Abstract We present a study on inclusive emissions of double $$\Lambda _c$$ Λ c or plus light-flavored jet system as probe channels in the semi-hard regime QCD. Our formalism relies so-called hybrid high-energy/collinear factorization, where standard collinear descripti...
