Probing the existence of a new charged vector boson decaying into heavy neutral leptons using ultra-peripheral heavy ion collisions at ATLAS
Y. M. Oviedo-Torres, Sebastian Tapia, J. Zamora-Saa
In this paper we explore the potential of Ultra-peripheral Collisions at the LHC to investigate new physics, focusing on the production of new charged vector bosons tha…
Improved limits on a new in scenarios with the NA64 experiment at CERN
The NA64 Collaboration, Yu. M. Andreev, A. Antonov +53
Extensions of the Standard Model featuring an additional gauge symmetry provide a compelling framework linking the origin of neutrino masses to possible dark matter ca…
Can the FCC-hh prove the B-L gauge symmetry?
Farinaldo S. Queiroz, J. Zamora-Saa, Ricardo C. Silva +1
We present a phenomenological study of the discovery potential at the FCC-hh for a new heavy neutral vector boson, Z', predicted by the gauge symmetry. Focusing on the…
Search for sub-GeV Scalars in collisions
D. Cogollo, Y. M. Oviedo-Torres, Farinaldo S. Queiroz +2
Light scalars that couple to leptons are common figures in beyond the Standard Model endeavors. Considering a scalar that has universal and couplings to leptons only, we compute th…
The SND@LHC neutron shielding
LHC Collaboration
The design and construction of a neutron shielding for the SND@LHC detector, which utilizes a combination of plexiglass and borated polyethylene, is presented. FLUKA simulations we…
Searching for Light Dark Matter and Dark Sectors with the NA64 experiment at the CERN SPS
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +49
Since its approval in 2016, NA64 has pioneered light dark matter (LDM) searches with electron, positron, muon, and hadron beams. The experiment has successfully met its primary obj…
