A Note on analytic formulas of Feynman propagators in position space
Hong-Hao Zhang, Kai-Xi Feng, Si-Wei Qiu +2
In this paper, we correct an inaccurate result of previous works on the Feynman propagator in position space of a free Dirac field in (3+1)-dimensional spacetime, and we derive the…
New Terms for the Compact Form of Electroweak Chiral Lagrangian
Hong-Hao Zhang, Wen-Bin Yan, J. K. Parry +1
The compact form of the electroweak chiral Lagrangian is a reformulation of its original form and is expressed in terms of chiral rotated electroweak gauge fields, which is crucial…
Trace Formulae of Characteristic Polynomial and Cayley-Hamilton's Theorem, and Applications to Chiral Perturbation Theory and General Relativity
Hong-Hao Zhang, Wen-Bin Yan, Xue-Song Li
By using combinatorics, we give a new proof for the recurrence relations of the characteristic polynomial coefficients, and then we obtain an explicit expression for the generic te…
The Oblique Corrections from Heavy Scalars in Irreducible Representations
Hong-Hao Zhang, Wen-Bin Yan, Xue-Song Li
The contributions to , , and from heavy scalars in any irreducible representation of the electroweak gauge group are obtained. We find that in the…
