Contact interactions between particle worldlines [PDF]
Journal of High Energy Physics, 2016 We construct contact interactions for bosonic and fermionic point particles. We first relate the resulting theories to classical electrostatics by taking functional averages over worldlines whose endpoints are fixed to charged particles. Counting those paths which pass through a space-time point $x^ $ gives the static electric field at that point ...

Contact Interactions: Results from ZEUS and a Global Analysis [PDF]
, 1999 In a search for signatures of physics processes beyond the Standard Model, various eeqq vector contact interaction hypotheses have been tested in the ZEUS experiment. No significant evidence of a contact interaction signal has been found. The analysis is

CONTACT INTERACTIONS OF FREE ANYONS [PDF]
Modern Physics Letters A, 1995 The possibility of the existence of “free” Schrödinger anyons is considered. It is shown that special type of contact interactions exists when scattering does not arise. By formulating the problem for the two-particle system with a finite region of interaction which is then allowed to go to zero, it is established that this type of the contact ...

A Note on the Exact Green Function for a Quantum System Decorated by Two or More Impurities
Frontiers in Physics, 2019 The exact Green function is constructed for a quantum system, with known Green function, which is decorated by two delta function impurities. It is shown that when two such impurities coincide they behave as a single singular potential with combined ...
