Pentaquark update after ten years

Pentaquark Update After Ten Years

Studying scattering of heavy flavor hadrons and looking for bound states is shown to give experimental information otherwise unobtainable about effective two-body interactions between constituent (qq)6 and (q̄q)8 pairs respectively in color sextet and color octet states. All the successes of the constituent quark model in (uds) hadron spectroscopy are shown to depend only on effective two-body i...

Ten Years After: An Update on TG/2 (and Friends)

Since its first implementation in 1995, the shallow NLG system TG/2 has been used as a component in many NLG applications that range from very shallow template systems to in-depth realization engines. TG/2 has continuously been refined, the Java brother implementation XtraGen has become available, and the grammar development environment eGram today allows for designing grammars on a more abstra...

Bves: ten years after.

Bves was discovered in 1999 by two independent laboratories using screens to identify novel genes that were highly expressed in the developing heart (Reese et al., 1999; Andree et al., 2000). As an evolutionarily conserved transmembrane protein, Bves is postulated to play a role in cell adhesion and cell motility. In studies of Bves protein disruption, there have been multiple phenotypes, but f...

– 1– Pentaquark Update

In 2003, the field of baryon spectroscopy was almost revolutionized by experimental evidence for the existence of baryon states constructed from five quarks (actually four quarks and an antiquark) rather than the usual three quarks. In a 1997 paper [1], considering only u, d, and s quarks, Diakonov et al. proposed the existence of a low-mass anti-decuplet of pen-taquark baryons, with spin 1/2 a...
