Cosmological Scattering Equations at Tree-level and One-loop
Humberto Gomez, Renann Lipinski Jusinskas, Arthur Lipstein
We recently proposed a formula for tree-level -point correlators of massive theory in de Sitter momentum space which consists of an integral over punctures on the Riem…
Multiparticle solutions to Einstein's equations
Humberto Gomez, Renann Lipinski Jusinskas
In this letter we present the first multiparticle solutions to Einstein's field equations in the presence of matter. These solutions are iteratively obtained via the perturbiner me…
Cosmological Scattering Equations
Humberto Gomez, Renann Lipinski Jusinskas, Arthur Lipstein
We propose a worldsheet formula for tree-level correlation functions describing a scalar field with arbitrary mass and quartic self-interaction in de Sitter space, which is a simpl…
Extra gauge bosons and lepton flavor universality violation in and meson decays
Cristian H. García-Duque, J. H. Muñoz, Néstor Quintero +1
Lepton flavor universality can be tested through the ratio of semileptonic meson decays and leptonic meson decays, with (). For the charged-current…
Tests of the Atomki anomaly in lepton pair decays of heavy mesons
G. López Castro, Néstor Quintero
The anomalies recently reported in lepton pair transitions of Be and He nuclei may be attributed to the existence of a feebly interacting light vector boson . We s…
