The 〈 SPP 〉 Green Function and SU ( 3 ) Breaking in K l 3 Decays ∗
Using the 1/N C expansion scheme and truncating the hadronic spectrum to the lowest-lying resonances, we match a meromorphic approximation to the SP P Green function onto QCD by imposing the correct large-momentum falloff, both off-shell and on the relevant hadron mass shells. In this way we determine a number of chiral low-energy constants of O(p 6), in particular the ones governing SU (3) bre...
متن کاملcompactifications and function spaces on weighted semigruops
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
15 صفحه اولCadherin function: Breaking the barrier
Three desmoglein isoforms collaborate with desmocollins to build the adhesive core of desmosomes. A recent study has shown that altering the ratio of desmoglein isoforms influences epidermal barrier function, suggesting distinct roles for these cadherins that extend beyond adhesion.
متن کاملChiral symmetry breaking via multifermion Green functions.
Previous results on fermion chirality-flipping four-point functions are extended to SU(N) gauge theories. The problem is purely non-perturbative, and it is approached by truncating the Schwinger-Dyson hierarchy. The large-N limit also simplifies the problem substantially. The resulting equation is solved numerically by relaxation techniques and an estimate of the critical coupling and momentum ...
متن کاملThe Breaking of the AR Hash Function
The AR hash function has been proposed by Algorithmic Research Ltd and is currently being used in practice in the German banking world. AR hash is based on DES and a variant of the CBC mode. It produces a 128 bit hash value. In this paper, we present two attacks on AR hash. The rst one constructs in one DES encryption two messages with the same hash value. The second one nds, given an arbitrary...
