Meson Resonances at large Nc: Complex Poles vs Breit-Wigner Masses [PDF]
, 2009 The rigorous quantum mechanical definition of a resonance requires determining the pole position in the second Riemann sheet of the analytically continued partial wave scattering amplitude in the complex Mandelstam s-variable plane.

The Landau Pole at Finite Temperature [PDF]
, 2001 We study the Landau pole in the lambda phi^4 field theory at non-zero and large temperatures. We show that the position of the thermal Landau pole Lambda_L(T) is shifted to higher energies with respect to the zero temperature Landau pole Lambda_L(0).

Exact Calculation of Ring Diagrams and the Off-shell Effect on the Equation of State [PDF]
, 2003 The partition function with ring diagrams at finite temperature is exactly caluclated by using contour integrals in the complex energy plane. It contains a pole part with temperature and momentum dependent mass and a phase shift part induced by off-shell

Pseudoscalar Vertex, Goldstone Boson and Quark Masses on the Lattice [PDF]
, 1998 We analyse the Structure Function collaboration data on the quark pseudoscalar vertex and extract the Goldstone boson pole contribution, in 1/p2. The strength of the pole is found to be quite large at presently accessible scales.

On the position of a heavy Higgs pole [PDF]
, 1996 Higher loop calculations in the Higgs sector of the standard model at the Higgs mass scale have shown that perturbation theory diverges very badly at about 1 TeV in the on-shell renormalization scheme.

Changer in the texture orientation of electrolytic nickel by cold air plasma
Литьë и металлургия, 2020 The effects of cold air plasma influence on the change in the microstructure, stress state and texture of the cathode nickel brand H-1 were studied. By the method of target metallography it has been established that the microstructure does not change ...

More on ambiguities in the pole mass [PDF]
, 1994 The relation between the pole quark mass and the $\overline{MS}$-renormalized mass is governed by an infrared renormalon singularity, which leads to an ambiguity of order $\Lambda_{QCD}$ in the definition of the pole mass.

Race to the Pole: Matthew Henson, Arctic Explorer
American Studies in Scandinavia, 2022 In his memoir, A Negro Explorer at the North Pole (1912), Matthew Henson describes the toll of his and Peary’s race to the Pole. This record of the 1908-09 Arctic expedition complicates established understandings of the “Dash to the Pole” and his own ...

Direct resummation of the leading renormalons in inclusive semileptonic B decay [PDF]
, 2002 We present a Borel resummation method for the QCD corrections in inclusive, charmless, semileptonic B meson decay. The renormalon contributions are resummed to all orders by employing a bilocal expansion of the Borel transform that accurately accounts ...
