We study the properties of open-charm mesons (D and ¯ D) in nuclear matter at finite temperature within a self-consistent coupled-channel approach. The meson-baryon interactions are adopted from a type of broken SU(4) s-wave Tomozawa-Weinberg terms supplemented by an attractive scalar-isoscalar interaction. The in-medium solution at finite temperature(More)
This analysis studies the reaction ep → e p φ in the kinematical range 1.6 ≤ Q 2 ≤ 3.8 GeV 2 and 2.0 ≤ W ≤ 3.0 GeV at CLAS. After successful signal identification, total and differential cross sections are measured and compared to the world data set. Comparisons are made to the predictions of the Jean-Marc Laget(JML) model based on Pomeron plus 2-gluon(More)
The D and D mesons are studied in hot dense matter within a self-consistent coupled-channel approach taking, as bare interaction, a broken SU(4) s-wave Tomozawa-Weinberg interaction supplemented by an attractive isoscalar-scalar term. The in-medium solution at finite temperature incorporates Pauli blocking effects, baryon mean-field bindings, and π and(More)
Previous approaches to the photo-and electro-production of strangeness off the proton, based upon effective hadronic Lagrangians, are extended here to incorporate the so called off-shell effects inherent to the fermions with spin ≥ 3/2. A formalism for intermediate-state, spin 3/2, nucleonic and hyperonic resonances is presented and applied to the processes(More)
Space charge formation in polyimide films, and therefore, charge injection from the electrodes largely depend upon the water content. In order to clarify the injection properties of positive and negative charge carriers, space charge distributions were observed in the polyimide films with different electrode conditions, such as aluminium was evaporated on a(More)
The DSC curve, the DC current and the space charge distribution have been measured on polypropylene (H-PP), block copolymer (B-PP) and random copolymer (Z-PP) copolymerized with Ziegler catalyst, and M-PP copolymerized with metallocene catalyst. The copolymers have 3.0~4.5 wt% of ethylene. B-PP with 4.5 wt% of ethylene had similar DSC curve and space charge(More)
The purpose of the present discussion is to supplement the talk, by B. Saghai at this workshop, on the study of the electromagnetic production of strangeness on the nucleon based upon effective Lagrangian methods. Here we focus on the proper treatment of the spin 3/2 resonances and their associated effects due to the spin 1/2 component of the corresponding(More)
We study the properties of strange and charm mesons in hot and dense matter within a self-consistent coupled-channel approach for the experimental conditions of density and temperature expected for the CBM experiment at FAIR/GSI. The in-medium solution at finite temperature accounts for Pauli blocking effects, mean-field binding on all the baryons involved,(More)
Physics (ABSTRACT) An alternative approach to the problem of CP-violation is presented. It is based on the possibility of spontaneous CP-breakdown in models with two Higgs doublets. General features of the phenomenon such as stability of the vacuum and the existence of a light axion are discussed. We investigate the feasibility of spontaneously broken CP in(More)
