Quantum Entanglement of the Final Particles in the Resonant Trident Pair Production Process in a Strong Electromagnetic Wave

Photonics
The resonant trident pair production process in the collision of ultrarelativistic electrons with a strong electromagnetic wave was theoretically studied. Under resonant conditions, the intermediate virtual gamma-quantum became real. As a result, the original resonant trident pair production process effectively split into two first-order processes by ...

Search for a resonance decaying to a W boson and a photon in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV using leptonic W boson decays

Journal of High Energy Physics
A search for a new charged particle X with mass between 0.3 and 2.0 TeV decaying to a W boson and a photon is presented, using proton-proton collision data at a center-of-mass energy of 13 TeV, collected by the CMS experiment and corresponding to an ...

First observation of strange baryon enhancement with effective energy in pp collisions at the LHC

Journal of High Energy Physics
The production of (multi-)strange hadrons is measured at midrapidity in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV as a function of the local charged-particle multiplicity in the pseudorapidity interval |η| < 0.5 and of the very-forward energy

A mechanism of resonant particle production during inflation

Tipicamente, o paradigma inflacionário padrão coloca o periodo de "reheating" estritamente após o término do regime de "slow-roll" do inflatão. Várias propostas de mecanismos de produção de partículas durante a fase de "slow-roll" têm surgido ao longo dos anos, sendo um argumento em seu favor a possibilidade de ter assinaturas observáveis dessas ...
