How strange a non-strange heavy baryon?
We give some general arguments in favor of the large magnitude of matrix elements of an operator associated with nonvalence quarks in heavy hadrons. We estimate matrix element 1 2mΛb 〈Λb|s̄s|Λb〉 ≃ 1 ÷ 2 for Λb baryon whose valence content is b, u, d quarks. This magnitude corresponds to a noticeable contribution of the strange quark into the heavy baryon mass 1 2mΛb 〈Λb|mss̄s|Λb〉 ≃ 200 ÷ 300MeV ....
متن کاملIn a Strange Land
Ignorance of the culture and traditions of immigrants leads to misunderstanding and is a factor in mental illness among people whose new home seems intimidating as Dr. Farrukh Hashmi, a psychiatrist and a member of the Midlands Race Relations Board, explains. an immigrant was taken to a mental hospital because he was said to have been aggressive, had been shouting at his family, and he had thre...
متن کاملA strange gait.
A 5-year-old afebrile girl presented to the office with an antalgic limp and left foot pain that lasted 3 weeks. On physical examination, swelling and redness were present and the top of the midfoot was painful to touch. Weight-bearing radiographs of the 2 feet were obtained (Figures 1-3; Figures 1 and 2 available at www.jpeds.com). The left foot navicular bone appears “wafer like”—flattened wi...
متن کاملA strange experience
In order to survive life’s traumatic experiences, we tend to push them to one side in our quest for survival. My experience of surgery for epilepsy certainly comes into this category. My epilepsy is long-standing and dates back to midadolescence. The seizures have remained largely intractable to medical treatment and it was only with the advent of routine neuroimaging some years later that it b...
متن کاملA Strange Mesonic
The strange-quark vector current ρ-to-π meson transition form factor is computed at one-loop order using strange meson intermediate states. A comparison is made with a φ-meson dominance model estimate. We find that one-loop contributions are comparable in magnitude to those predicted by φ-meson dominance. It is possible that the one-loop contribution can make the matrix element as large as thos...
