Mass – dependence of the Λ hypernuclear decay widths
Two different approaches have been employed for the evaluation of the decay widths of Λ–hypernuclei (ranging from 5 Λ He to 208 Λ Pb) with the polarization propagator method. In ref. [1], the two–nucleon stimulated non–mesonic decay, ΛNN → NNN, has been parameterized phenomenologically by means of data on the pion–nucleus optical potential. The other approach [2] consisted in a fully microscopi...
متن کاملTransversity and Λ Polarization
Two related issues are discussed, which might be easily explored by present and future COMPASS experiments. The first one deals with the new world of transversity, the fundamental polarized parton distribution so far totally unknown. The second issue concerns Λ production in polarized semi-inclusive processes, with a measurement of the Λ polarization, which might give novel information on distr...
متن کاملThe contribution of Σ ∗ → Λ π to measured Λ polarization †
Calculations of the polarization of Λ and ¯ Λ particles after fragmentation of a polarized quark produced in processes like Z-decay and deep inelas-tic polarized lepton scattering must include Λ and ¯ Λ produced as decay products of Σ 0 and Σ * as well as those produced directly. These decay contributions are significant and not feasibly included in theoretical calculations based on QCD without...
متن کاملTransverse Λ Polarization at LHC
Transverse polarization of Λ hyperons produced in p p and p Pb collisions is discussed. A factorized description in the intermediate to high pT region is considered that involves transverse momentum and spin dependence in the fragmentation process. Consequences and suggestions for investigations at LHC are pointed out for the process p+ p → Λ + jets +X at midrapidity and p+ p/Pb → Λ +X in the f...
متن کاملPolarization Dependence of Emissivity
where i, r, and t label the incident, reflected, and transmitted waves, respectively. The solution is based on the fact that eq. (1) holds separately for each polarization of the emitted radiation, and is also independent of the angle of the radiation. This result is implicit in Planck’s derivation [5] of Kirchhoff’s law of radiation, and is stated explicitly in [6]. That law describes the ther...
