“…Naturally, this very proximity of theN N threshold suggests that theN N channel should have something to do with the appearance of that structure in the multipion production cross sections. A common speculation is that it could be a signal for app bound state [4,7] or a subtresholdpp resonance [5]. Such a conjecture seems to be also in line with experimental findings in a related reaction, namely e + e − →pp, where a near-threshold enhancement seen in the cross section [8,9] is likewise associated with a possiblepp bound state, cf.…”

Origin of the structures observed ine+e−annihilation into multipion states around thep¯pthreshold

We analyze the origin of the structures observed in the reactions e + e − → 3(π + π − ), 2(π + π − π 0 ), ωπ + π − π 0 , and e + e − → 2(π + π − )π 0 around the antiproton-proton (pp) threshold. We calculate the contribution of the two-step process e + e − →N N → multipions to the total reaction amplitude. The amplitude for e + e − →N N is constrained from near-threshold data on the e + e − →pp cross section and the one forN N → multipions can be likewise fixed from available experimental information, for all those 5π and 6π states. The resulting amplitude for e + e − → multipions turns out to be large enough to play a role for the considered e + e − annihilation channels and, in three of the four reactions, even allows us to reproduce the data quantitatively near theN N threshold. The structures seen in the experiments emerges then as a threshold effect due to the opening of theN N channel.

“…Phenomenological fits to the e + e − data locate the structure at 1.91 GeV [7] or at 1.86-1.88 GeV [2] while thepp threshold is at 1.8765 GeV. Naturally, this very proximity of theN N threshold suggests that theN N channel should have something to do with the appearance of that structure in the multipion production cross sections.…”

“…Parenting style chosen must be most appropriate for their children, in accordance with the dual responsibilities or roles that she is juggling with. As the study by Bornstein and Zlotnik (2008) explains that socioeconomic status, parental education level, and mother's employment status can affect the parenting. A working mother might have feelings of guilt as they may not be able to guide and give attention to their children full time.…”

The trend of working mothers is not uncommon anymore, starting from a desire to improve the economic status of the families to the desire for self-actualization, combined with the increasing number of women with higher education. Malaysian women comprise 50% of the work force, and 70% of them are married working women (Sabil & Marican, 2010). Mother and child interaction is very important for the development of the child. Each of the working mothers' parenting style chosen must be appropriate for their children, in accordance with the dual responsibilities or roles that she is juggling with. A working mother who is not able to guide and give full attention to their children might have a negative impact on the child's developmental outcomes. Thus, this study aimed to look at the relationship between parenting satisfaction and parenting style of working mothers. This study was conducted with 62 working mothers in Sultan Idris Education University who work for an average of 15-32 hours per week. They were 22-40 years old with children under 15 years old. These mothers completed the Parenting Satisfaction Scale (PSS) as a measure of parenting satisfaction and the Parenting Style Dimensions Questionnaire (PSDQ) to measure their parenting styles. The results of this study indicated that the working mothers tended to adopt the authoritative parenting style in their parenting practice, and the majority reported moderate level of parenting satisfaction. The results also showed there were differential relationships between parenting style and parenting satisfaction in the working mothers.

“…Although the detailed mechanism of its appearance remains unsettled, the very recent analysis [28] sees it as a result of interplay of several resonances with J P C = 1 −− (including ρ(1700)) and a background. This analysis was explicitly based on the vector dominance idea and explicitly uses the assumption that the 6π spectra in e + e − annihilation and in diffractive photoproduction are essentially the same (apart from kinematical factors).…”

Production of spin-3 mesons in diffractive DIS

We calculate the amplitudes of J P C = 3 −− meson production in diffractive DIS within the k t -factorization approach, with a particular attention paid to the ρ 3 (1690) meson. We find that at all Q 2 the ρ 3 (1690) production cross section is 2-5 times smaller than the ρ(1700) production cross section, which is assumed to be a pure D-wave state. Studying σ L and σ T separately, we observe domination of ρ 3 in σ L and domination of ρ(1700) in σ T and offer an explanation of this behavior in simple terms. We also find very strong contributions -sometimes even domination -of the s-channel helicity violating amplitudes. The typical color dipole sizes probed in ρ 3 production are shown to be larger than those in the ground state ρ production, and the energy dependence of ρ 3 cross section turns out to be much flatter than the ρ production cross section. All the conclusions about the relative behavior of ρ 3 (1690) and ρ(1700) mesons are numerically stable against variations of input parameters.
