Probing leptophobic dark sector with a pseudoscalar portal in the NA64 experiment at CERN

open access: yesJournal of High Energy Physics
We propose the possibility of discovering a light pseudoscalar particle a, axion-like particle (ALP), interacting mainly with quarks using the electron and photon scattering reaction chain e + Z → e + γ + Z; γ + Z → a + Z on nuclei in the NA64 experiment

Search for dark matter produced in association with one or two top quarks in proton-proton collisions at $$\sqrt{\text{s}}$$ = 13 TeV

open access: yesJournal of High Energy Physics
A search is performed for dark matter (DM) produced in association with a single top quark or a pair of top quarks using the data collected with the CMS detector at the LHC from proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding

Exploring multi-step electroweak phase transitions in the 2HDM+ $$\varvec{a}$$ a

open access: yesEuropean Physical Journal C: Particles and Fields
Multiple electroweak phase transitions occurring sequentially in the early universe can give rise to intriguing phenomenology, compared to the typical single-step electroweak phase transition.
