Design of an atmospheric muon tomographer for material identification based on CORSIKA+ GEANT4 simulations
In recent years, muon tomography has appeared as a powerful and innovative technique for non-invasive imaging of both large and small structures, with applications in different fields such as geology,...

Probing displaced (dark)photons from low reheating freeze-in at the LHC
We extend the Standard Model (SM) by introducing a U(1)′ gauge boson and a real pseudo-scalar field, both odd under a ℤ2​ symmetry. The resulting low-energy spectrum consists of a...

Opening the parameter space of sub-GeV inelastic dark matter through parity violation
Sub-GeV dark matter (DM) has emerged as a particularly compelling target in light of the persistent null results from conventional DM searches. While s-wave annihilating DM candidates with masses below...

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...

Bounds on neutrino-DM interactions from TXS 0506+056 neutrino outburst
We constrain the neutrino-dark matter cross-section using the 13±5 neutrino event excess observed by IceCube in 2014-2015 from the direction of the blazar TXS 0506+056. Our analysis takes advantage of...

Probing triple-gauge couplings in anomalous gauge theories at hadron and lepton colliders
Gauge anomalous quantum field theories are inconsistent as full UV theories since they lead to the breaking of Lorentz invariance or Unitarity, as well as non-renormalizability. It is well known,...

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...
