A narrow "peanut" pentaquark
We analyse the decay Θs(1/2)→ NK in a non-relativistic Fock space description using three and five constituent quarks for the nucleon and the pentaquark, respectively. Following Jaffe and Wilczek [1], we assume that quark-quark correlations in spin-zero state play an important role for the pentaquark internal structure. Within this scenario, a strong dynamical suppression of the decay width is ...
متن کاملActivation through a Narrow Opening
The escape of Brownian motion through a narrow absorbing window in an otherwise reflecting boundary of a domain is a rare event. In the presence of a deep potential well, there are two long time scales, the mean escape time from the well and the mean time to reach the absorbing window. We derive a generalized Kramers formula for the mean escape time through the narrow window.
متن کاملA Narrow QRS Complex Tachycardia:
An 80-year-old man underwent an electrophysiologic procedure because of recurrent episodes of supraventricular tachycardia. Episodes of nonsustained narrow QRS complex tachycardia occurred spontaneously after catheter placement. Examples of the onset and termination of an episode of tachycardia are shown in Figures 1 and 2, respectively. What is the mechanism of the tachycardia? What is the lev...
متن کاملStepping from a narrow support.
The study addresses postural preparation to stepping. In particular, it tests a hypothesis that such preparation involves adjustments in the activity of ankle plantarflexors to produce shifts of the center of pressure. We investigated the initiation of a step from quiet stance when the subjects stood on boards with a decreased dimension of the support area in the anterior-posterior direction ("...
متن کاملA narrow QRS gallop rhythm
The QRS complexes 1, 2, 4, 5 and 7 are not preceded by atrial activation. The QRS morphology is slightly different from an A-V conducted beat (QRS 3, 6). Therefore an origin in the bundle branch system is presumed for beats 1, 2, 4, 5 and 7. An escape beat (QRS 2, 5) is retrogradely conducted to the atrium with atrial activation followed by AV conduction and ventricular capture (#3, 6). This ph...
