Dress code for infrared safe scattering in QED
Hayato Hirai, Sotaro Sugishita
We study the -matrix and inclusive cross-section for general dressed states in quantum electrodynamics. We obtain an infrared factorization formula of the -matrix elements fo…
IR finite S-matrix by gauge invariant dressed states
Hayato Hirai, Sotaro Sugishita
Dressed states were proposed to define the infrared (IR) finite -matrix in QED or gravity. We show that the original Kulish-Faddeev dressed states are not enough to cure the IR…
Nonlinear sigma model in discrete complex analysis
Masaru Kamata, Masayoshi Sekiguchi, Yuuki Tadokoro
We present a discrete version of the two-dimensional nonlinear sigma model examined by Belavin and Polyakov. We formulate it by means of Mercat's discrete complex analysis a…
A q-analog of the ADHMN construction and axisymmetric multi-instantons
Masaru Kamata, Atsushi Nakamula
In the preceding paper (Phys. Lett. B463 (1999) 257), the authors presented a q-analog of the ADHMN construction and obtained a family of anti-selfdual configurations with a parame…
One-parameter family of selfdual solutions in classical Yang-Mills theory
Masaru Kamata, Atsushi Nakamula
The ADHM construction, which yields (anti-)selfdual configurations in classical Yang-Mills theories, is applied to an infinite dimensional l^2 vector space, and as a consequence, a…
