Gamma/hadron separation using the arrival time distribution of particle cascades at TeV energies for SWGO
Given the success of high-altitude wide-field gamma-ray detectors, such as HAWC and LHAASO, we explore a new gamma-hadron separation variable for the future Southern Wide-field Gamma-ray Observatory (SWGO), currently in...

Distinguishing beyond-standard model effects in neutrino oscillation
We systematically assess the DUNE experiment's ability to distinguish between various beyond-standard neutrino oscillation hypotheses pair combinations. For a pair comparison, we evaluate the statistical separation, where one hypothesis plays...

From WIMPs to FIMPs: impact of early matter domination
In the context of non-standard cosmologies, an early matter-dominated (EMD) era cansignificantly alter the conventional dark matter (DM) genesis. In this work, we reexamine theimpact of an EMD on the...

Indirect search of heavy neutral leptons using the DUNE near detector
We evaluate the potential of the DUNE near detector (DUNEND) for establishing bounds for heavy neutral leptons (HNLs). This is achieved by studying how the presence of HNLs affects the...

Quantum decoherence effects on precision measurements at DUNE and T2HK
We investigate the potential impact of neutrino quantum decoherence on the precision measurements of standard neutrino oscillation parameters in the DUNE and T2HK experiments. We show that the measurement of...

Bounding the Dimension-5 Seesaw Portal with non-pointing photon searches
The addition of d = 5 operators to the Seesaw model leads to the Dimension-5 Seesaw Portal. Here, two new operators provide interactions for the heavy sterile neutrinos. In particular,...

Quantum decoherence effects: A complete treatment
Physical systems in real life are inextricably linked to their surroundings and never completely separated from them. Truly closed systems do not exist. The phenomenon of decoherence, which is brought...

From WIMPs to FIMPs with low reheating temperatures
Weakly- and Feebly-Interacting Massive Particles (WIMPs and FIMPs) are among the best-motivated dark matter (DM) candidates. In this paper, we investigate the production of DM through the WIMP and FIMP...

On the sensitivity reach of LQ production with preferential couplings to third generation fermions at the LHC
Leptoquarks (LQs) are hypothetical particles that appear in various extensions of the Standard Model (SM), that can explain observed differences between SM theory predictions and experimental results. The production of...

Can SUSY relax lepton number violation constraints coming from loop corrections to light neutrino masses on the low-scale seesaw mechanism?
Heavy neutrinos from the type-I seesaw model can have a large mixing with active states, motivating their search at collider experiments. However, loop corrections to light neutrino masses constrain...
