Implications of the Glueball-qq filter on the 1 nonet
The application of our glueball-qq̄ filter to the centrally produced KK̄π system shows that the f1(1285) and f1(1420) have the same behaviour; namely consistent with the f1(1420) being the partner to the f1(1285) in the P1 nonet of axial mesons. We determine a flavour singlet-octet mixing angle of ∼ 50 for this nonet and highlight that the existence of the supposed f1(1510) needs confirmation. e-...
متن کاملComment on “Understanding the scalar meson q¯q nonet” hep-ph/9806246
It is shown that the incomplete scalar meson nonets found by Törnqvist [1] and Törnqvist & Roos [2], employing a new version of the Helsinki unitarized quark model, should in fact be complete, including an as yet unconfirmed light K 0 below 1 GeV (old κ) and the established f0(1500). A detailed comparison is presented with the predictions of the Nijmegen unitarized meson model, in which two com...
متن کاملsurvey on the rule of the due & hindering relying on the sheikh ansaris ideas
قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
15 صفحه اولA Glueball-q Q Lter in Central Hadron Production
We have stumbled upon a remarkable empirical feature of central meson production which separates established q q mesons from glueball candidates. This does not appear to have been noted previously and we have no simple explanation for it. We suggest that glueballs and q q of the same J PC are distinguishable due to their boson versus fermion internal structure and that this leads to a diierent ...
متن کاملthe impact of morphological awareness on the vocabulary development of the iranian efl students
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
