Electroweak effects in the double Dalitz decay Bs→l+l−l′+l′−
Physics Letters B, 2003 We investigate the double Dalitz decays $B_s \to l^+ l^- l'^+ l'^-$ on the basis of the effective Hamiltonian for the transition $b \bar{s} \to l^+ l^-$, and universal form factors suggested by QCD. The correlated mass spectrum of the two lepton pairs in the decay $B_s \to e^+ e^- ^+ ^-$ is derived in an efficient way, using a QED result for meson ...

Acoustic investigation on nozzles with different types of six lobed chevrons [PDF]
INCAS Bulletin, 2013 This paper deals with a few aspects of the notion of chevron and the process that helps reducing the noise pollution. Based on the gas dynamic and geometrical parameters of a single flow jet engine a model of CFD data processing is made.

Rare $B\to \pi l\bar l$ and $B\to\rho l \bar l$ decays in the relativistic quark model [PDF]
, 2014 The branching fractions of the rare weak $B\to \pi l^+l^-(\nu\bar\nu)$ and $B\to\rho l^+l^-(\nu\bar\nu)$ decays are calculated in the framework of the relativistic quark model based on the quasipotential approach.

Electronic Notes in Theoretical Computer Science, 1997 AbstractThe equivalence problem for deterministic pushdown automata is shown to be decidable. We exhibit a complete formal system for deducing equivalent pairs of deterministic rational boolean series on the alphabet associated with a dpda M.
