REGULAR ARTICLES Twist singularities for symplectic maps
Near a nonresonant, elliptic fixed point, a symplectic map can be transformed into Birkhoff normal form. In these coordinates, the dynamics is represented entirely by the Lagrangian ‘‘frequency map’’ that gives the rotation number as a function of the action. The twist matrix, given by the Jacobian of the rotation number, describes the anharmonicity in the system. When the twist is singular the...
متن کاملMass singularities in light quark correlators: The strange quark case.
The correlators of light-quark currents contain mass-singularities of the form log(m 2 /Q 2). It has been known for quite some time that these mass-logarithms can be absorbed into the vacuum expectation values of other operators of appropriate dimension, provided that schemes without normal-ordering are used. We discuss in detail this procedure for the case of the mass logarithms m 4 log(m 2 /Q...
متن کاملComplex Singularities and Twist Quantum Fields
In this thesis, we give an expository overview of the work of John Milnor concerning the topology of functions f : Cm → C of several complex variables with a singular point at the origin. In particular, we focus on a certain fibration of the set S2n+1 \ f−1(0) over the circle, where S2n+1 is a hypersphere of sufficiently small radius about the origin. We relate this work to more recent discover...
متن کاملQuark Distributions of Octet Baryons from SU(3) Symmetry
SU(3) symmetry relations between the octet baryons are introduced in order to connect both the unpolarized and polarized quark distributions of the octet baryons with those of the nucleon. Two different parametrizations of the nucleon quark distributions are used. A new scenario of quark flavor and spin structure of the Λ is found and compared with two other models: a perturbative QCD based ana...
متن کامل0 Polarization in Hadronic Λ Hyperon Production and Twist - 3 Quark Distribution
Polarization of the Λ hyperon produced with a large transverse momentum in the unpolarized nucleon-nucleon collision is analyzed in the framework of QCD factorization. We focus on the mechanism in which the soft-gluon component of the chiral-odd spin-independent twist-3 quark distribution EF (x, x) becomes a source of the polarized quark fragmenting into the polarized Λ. Our simple model estima...
