Brazil: Authoritarianism and Class Control

Abstract

One of the most striking features of recent writing on comparative politics, especially the debate on underdevelopment, is the contribution made by Latin American theorists. Living in societies so strongly characterized by a culture of dependency, they have energetically developed and refined the theory of dependency. Directly experiencing the impact of imperialism and imperialism, they have carefully scrutinized and reassessed theories of imperialist control, and have explored the mechanisms of class interest, seeking to understand how such interests are maintained and expressed through the state apparatus, in policy making, the role of the bureaucracy, the armed forces, in cultural control and in the whole fabric of internal and external power relations.

Matrix elements of four-fermion operators with quenched Wilson fermions

“…Our final results are B D (µ = q * = 1/a) = 0.777 (15) and B Ds (µ = q * = 1/a) = 0.815 (9) . We now turn to the left-right operators which appear in the effective weak Hamiltonian due to electromagnetic penguin diagrams:…”

“…These results are consistent with those previously obtained (see, for example, the compilation in Refs. [5] and [15]), but have considerably smaller errors. The "perturbative error" reflects the dependence of the results on the choice of α s used in the matching of continuum and lattice operators, and is comparable to or larger than the statistical errors.…”

“…These convert to B D (µ = 2 GeV, q * = 1/a) = 0.785(15) and B Ds (µ = 2 GeV, q * = 1/a) = 0.822(10) . (6.3) The dependence on q * is, as for B K , smaller than the statistical errors.…”

Status of Lattice Flavor Physics

“…I believe the systematic uncertainties in calculations of f B and B K will soon reach the level where they too can be GeV 2 (0.5) 2 (0.9) 2 (1.1) 2 m 2 P = Figure 12. B K vs. mass of valence pseudoscalar meson computed on the n f = 2 UKQCD lattices with improved Wilson fermions [49]. Increasing κ implies decreasing m sea .…”

“…Unquenched data for B K using improved Wilson fermions recently appeared [49]. The authors note that the errors are too big and the sea quark masses are too large for reliable extrapolation to the physical masses.…”
