Color-Kinematics Duality and the Regge Limit of Inelastic Amplitudes
Agustin Sabio Vera, Eduardo Serna Campillo, Miguel A. Vazquez-Mozo
We investigate tree-level five-point amplitudes in scalar-QCD expressed in terms of Sudakov variables and find the equivalent "gravitational" counterparts using the color-kinematic…
New scalar field models and their defect solutions
D. Bazeia, M. A. Gonzalez Leon, L. Losano +1
In this work we introduce new scalar field models and study the defect solutions they may engender. The investigation is based on the deformation procedure, which greatly simplify…
On domain walls in a Ginzburg-Landau non-linear S^2-sigma model
Alberto Alonso-Izquierdo, Miguel Angel Gonzalez Leon, Juan Mateos Guilarte +1
The domain wall solutions of a Ginzburg-Landau non-linear -sigma hybrid model are unveiled. There are three types of basic topological walls and two types of degenerate famili…
Solitary Waves in Massive Nonlinear S^N-Sigma Models
A. Alonso Izquierdo, M. Á. González León, M. de la Torre Mayado
The solitary waves of massive (1+1)-dimensional nonlinear S^N-sigma models are unveiled. It is shown that the solitary waves in these systems are in one-to-one correspondence with…
BPS and non-BPS kinks in a massive non-linear S^2-sigma model
A. Alonso Izquierdo, M. A. Gonzalez Leon, J. Mateos Guilarte
The stability of the kinks of the non-linear -sigma model discovered in Phys. Rev. Lett. 101(2008)131602 is discussed from several points of view. After a direct est…
Gauge Theories, Duality Relations and the Tensor Hierarchy
Eric A. Bergshoeff, Jelle Hartong, Olaf Hohm +2
We compute the complete 3- and 4-dimensional tensor hierarchies, i.e. sets of p-form fields, with , which realize an off-shell algebra of bosonic gauge transformations…
