Chiral symmetry breaking condensates from baryonic sum rules
- Physics
- 1984
We analyse baryonic sum rules in order to determine chiral symmetry breaking condensates. We especially investigate the influence of the choice of the interpolating field and of the factorization…
Analysis of the triply heavy baryon states with the QCD sum rules
- PhysicsAAPPS Bulletin
- 2021
In this article, we reexamine the mass spectrum of the ground state triply heavy baryon states with the QCD sum rules by carrying out the operator product expansion up to the vacuum condensates of…
Analysis of the doubly heavy baryon states and pentaquark states with QCD sum rules
- PhysicsThe European Physical Journal C
- 2018
In this article, we study the doubly heavy baryon states and pentaquark states with the QCD sum rules by carrying out the operator product expansion up to the vacuum condensates of dimension 7 and 13…
Chiral extrapolation of nucleon wave function normalization constants
- Physics
- 2011
Within the framework of two-flavor covariant baryon chiral perturbation theory we have expressed the Chernyak-Zhitnitsky, Ioffe and Dosch currents in terms of chiral fields to provide leading…
Parity Projected QCD Sum Rule of the Nucleon with MEM
- Physics
- 2013
The nucleon and its negative-parity excited states are examined in a maximum entropy method analysis of QCD sum rules. We derive the parity projected nucleon sum rules with all known first order αs…

Singularities and Discontinuities of Feynman Amplitudes
- Physics, Mathematics
- 1960
The Landau singularities of the amplitude calculated from an arbitrary Feynman graph are considered. It is shown that the discontinuity across a branch cut starting from any Landau singularity is…
QUANTUM ELECTRODYNAMICS AT SMALL DISTANCES
- Physics
- 1954
The renormalized propagation functions DFC and SFC for photons and electrons, respectively, are investigated for momenta much greater than the mass of the electron. It is found that in this region…
Über Eigenschaften von Ausbreitungsfunktionen und Renormierungskonstanten quantisierter Felder

SummaryIt is attempted to derive some general properties of the propagation functions for coupled fields (ΔF′,SF′) without the use of power series expansions and to show their connection with the…
