On threshold amplitudes III: 2 into n processes
Joanna Domienik, Piotr Kosinski
The 2 into n scattering with final particles at rest is discussed. The comparison with purely soft processes allows to identify symmetries responsible for vanishing of certain 2 in…
Multiboson threshold production by fermion-antifermion pair and hidden symmetry
Joanna Domienik, Piotr Kosinski
We consider threshold production of arbitrary number of Higgs particles by fermion-antifermion pair. The nullification of amplitudes for the special case Higgs mass = 2 * fermion m…
On threshold amplitudes II: Amplitudes nullification via classical symmetries
Joanna Domienik, Piotr Kosinski
The Ward identities for amplitudes at the tree level are derived from symmetries of the corresponding classical dynamical systems. The results are applied to some 2 into n amplitud…
"Isochronic" dynamical systems and nullification of amplitudes
Joanna Domienik, Piotr Kosinski
We construct the set of theories which share the property that the tree-level amplitudes nullify even if both initial and final states contain the same type of particles. The origi…
