We review the calculation of the prompt lepton flux, produced in the atmosphere by the semileptonic decay of charmed particles. We describe side by side the intermediary ingredients used by different authors, which include not only the charm production model, but also other atmospheric particle showering parameters. After evaluating separately the relevance of each single ingredient, we analyze...
متن کامل$n$-cocoherent rings, $n$-cosemihereditary rings and $n$-V-rings
Let $R$ be a ring, and let $n, d$ be non-negative integers. A right $R$-module $M$ is called $(n, d)$-projective if $Ext^{d+1}_R(M, A)=0$ for every $n$-copresented right $R$-module $A$. $R$ is called right $n$-cocoherent if every $n$-copresented right $R$-module is $(n+1)$-coprese-nted, it is called a right co-$(n,d)$-ring if every right $R$-module is $(n, d)$-projective. $R$...

In this talk the gauge symmetry for Wilsonian flows in pure Yang-Mills theories is discussed. The background field formalism is used for the construction of a gauge invariant effective action. The symmetries of the effective action under gauge transformations for both the gauge field and the auxiliary background field are separately evaluated. Modified Ward-Takahashi and background field identi...

The neutron's EDM, dn, is calculated using a well-constrained Ansatz for the nucleon's Poincaré covariant Fadde'ev amplitude. The momentum-dependent quark dressing amplifies the contribution from the current-quarks' EDMs; and dressed-quark confinement and binding make distinguishable the effect of the two CP and T violating interactions: iγ5σµν (p1 − p2)ν and γ5(p1 + p2)µ, where p1,2 are the cu...

We present recent progress on the properties of antikaons in nuclei and dense nuclear matter as obtained from two ¯ KN interaction models: one based on the lowest-order meson-baryon chiral lagrangian and the other derived from a meson-exchange picture.
