Vector-Like Fermions and Inert Scalar Solutions to the Muon g-2 Anomaly and collider probes at the HL-LHC and FCC-hh
Á. S. de Jesus, F. S. Queiroz, J. W. F. Valle +1
We examine simple models with an inert scalar and vector-like leptons that can explain the recent measurement reported at FNAL. Prompted by this exciting result, we explore…
Constraining Gamma-ray Lines from Dark Matter Annihilation using Fermi-LAT and H.E.S.S. data
Lucia Angel, Guillermo Gambini, Leticia Guedes +2
Using 14 years of Fermi-LAT data and 10 years of H.E.S.S. observations in the direction of the galactic center, we derive limits on gamma-ray lines originated from dark matter anni…
The H0 trouble: Confronting Non-thermal Dark Matter and Phantom Cosmology with the CMB, BAO, and Type Ia Supernovae data
Simony S da Costa, Dêivid R da Silva, Álvaro S de Jesus +2
We have witnessed different values of the Hubble constant being found in the literature in the past years. Albeit, early measurements often result in an much smaller than tho…
Updated Big Bang Nucleosynthesis Bounds on Long-lived Particles from Dark Sectors
J. R. Alves, L. Angel, L. Guedes +5
As electromagnetic showers may alter the abundance of Helium, Lithium, and Deuterium, we can place severe constraints on the lifetime and amount of electromagnetic energy injected…
Constraints on Hidden Sectors Using Rare Kaon Decays
D. Cogollo, M. J. Neves, Tessio B. de Melo +3
The charged Kaon meson () features several hadronic decay modes, but the most relevant contribution to its decay width stems from the leptonic decay .…
Searching for a Leptophilic Z' and a 3-3-1 symmetry at CLIC
A. Alves, G. Gil da Silveira, V. P. Gonçalves +3
We derive the discovery potential of a leptophilic Z', and a Z' rising from a symmetry at the Compact Linear Collider (CLIC), which is planned…
Probing a Dark Sector with Collider Physics, Direct Detection, and Gravitational Waves
Giorgio Arcadi, Glauber C. Dorsch, Jacinto P. Neto +2
We assess the complementarity between colliders, direct detection searches, and gravitational wave interferometry in probing a scenario of dark matter in the early universe. The mo…
Toward a search for axion-like particles at the LNLS
L. Angel, P. Arias, C. O. Dib +8
Axion-Like Particles (ALPs) appear in several dark sector studies. They have gained increasing attention from the theoretical and experimental community. In this work, we propose t…
On the Role of LHC and HL-LHC in Constraining Flavor Changing Neutral Currents
S. Kovalenko, A. S. de Jesus, A. R. Zerwekh +5
The Standard Model (SM) has no flavor-changing neutral current (FCNC) processes at the tree level. Therefore, processes featuring FCNC in new physics are tightly constrained by dat…
Towards a Muon Collider
Carlotta Accettura, Dean Adams, Rohit Agarwal +294
A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions a…
