Are there impossible changes? θ > f but f ≯ θ

Θ ∗ partner to the Θ ( 1540 ) baryon

If the exotic baryon Θ(1540) is udud¯ s with J P = 1 2 + , we predict that there is a Θ * (1540− 1680) with J P = 3 2 +. The width Γ(Θ * → KN) is at least a factor of three larger than Γ(Θ). The possibilities of Θ * → KN π or Θγ via M 1 and E2 multipoles are discussed. A major plank in establishing the constituent quark model was the absence of baryons with strangeness +1. The announcement of s...

On (θ, θ)-Derivations in Semiprime Rings

What I F There Are No

Developing persuasive and consistent models of educational performance has proved elusive. Existing modelling suggests no clear relationship between resources and student performance. This mirrors observed policy outcomes. A possible explanation is that the achievement process is a complicated interactive one such that simple linear additive formulations break down. This analysis presents a sty...

فضاهای θ - همبند و θ- بستار

گیریم ( x, t) یک فضای توپولوژی باشد و x ? a. گوییم x به ?- بستار a متعلق است و می نویسیم x ? cl?a، هرگاه هر همسایگی بسته ی x مجموعه ی a را قطع کند. جفت (x, cl?) را یک فضای بستاری یا یک فضای همسایگی می نامیم. هرگاهa = cl?a ، آن گاه زیرمجموعه ی a را ?- بسته گوییم. مجموعه های ?- بسته، مجموعه های بسته در مجموعه ی xهمراه با توپولوژی جدید t? خواهند بود. توپولوژی نیم- منظم شده یt را با t?نشان می دهیم...

Different G F and sin 2 θ W for different processes

A natural theoretical framework is presented which allows for small departures from quark-lepton universality such that different G F and sin 2 θ W values are applicable for different processes.
