Evidence for the suppressed decay B(-)→DK(-), D→K(+)π(-).

The suppressed decay chain B(-)→DK(-), D→K(+)π(-), where D indicates a D(¯)(0) or D(0) state, provides important information on the CP-violating angle ϕ(3). We measure the ratio R(DK) of the decay rates to the favored mode B(-)→DK(-), D→K(-)π(+) to be R(DK)=[1.63(-0.

Observation of B(s)⁰→J/ψf₀(980) and evidence for B(s)⁰→J/ψf₀(1370).

We report the observation of B(s)⁰→J/ψf₀(980) and evidence for B(s)⁰→J/ψf₀(1370), which are CP eigenstate decay modes. These results are obtained from 121.4 fb⁻¹ of data collected at the Υ(5S) resonance with the Belle detector at the KEKB e(+)e⁻ collider.

[Typical CT findings with the intrathecal infusion test in post-traumatic disorders of cerebrospinal fluid dynamics].

Simultaneous computer tomographic and cerebrospinal fluid dynamics examinations in patients with high-pressure hydrocephalus, normal pressure hydrocephalus and cerebral atrophic processes are presented and discussed. Exclusive CT and MR examinations do not allow a differentiation of patients with normal pressure hydrocephalus and patients with cerebral atrophy. In the simultaneous examinations the morphological substrate during the intrathecal infusion test is represented.
