Past and current experiments have raised key open questions about the physics of charged cosmic rays and gamma rays, highlighting the need for a new generation of space missions to deepen our understanding. The challenge of achieving direct detection at higher energies, along with the demand for improved energy and angular resolution, is driving the development of next-generation detectors....

The direct detection of antimatter in cosmic rays is crucial for understanding the mechanisms driving their acceleration and propagation. It also serves as a powerful tool in the indirect search for dark matter. Traditionally, charge sign discrimination has relied on magnetic spectrometers. However, these instruments are not well suited for extending measurements to higher energies within...

NUSES is a space mission that will serve as a technological pathfinder for next-generation space-based detectors. Ziré, one of the two payloads onboard the satellite, is designed to measure the fluxes of electrons, protons, and light nuclei over a kinetic energy range from a few MeV up to several hundred MeV. It can also detect photons in the 0.1–10 MeV range for the study of transient...

The detector will be dedicated to measuring the fluxes of electrons, protons and light nuclei with kinetic energies from a few MeV up to hundreds of MeV.
These will enable the study of low-energy cosmic rays, Sun-Earth environment, space weather and magnetosphere-ionosphere-lithosphere coupling (MILC).

Accurate modelling of the sea-level muon flux is crucial for applications in particle physics, astrophysics, and geophysics, such as detector design and calibration, muon radiography and underground and neutrino physics experiments. While computationally efficient, traditional one-dimensional parameterisations often fall short in capturing the coupled dependencies of muon energy and zenith...

17. The ACROMASS project for the study of the charged components of the atmospheric cosmic radiationDr Catalin Frosin (INFN Firenze), Lorenzo Bonechi (Universita e INFN, Firenze (IT))23/07/2025, 18:30Cosmology, Astrophysics, Gravity, Mathematical PhysicsTalk
Although various measures of atmospheric muons have been conducted between the 60s and 80s of the last century, the study of these particles is still of interest in two different fields of physics. The first is related to neutrinos. The precise measurement of the parameters that describe the phenomenon of oscillation between the three families of neutrinos known so far, through the study of...

Dark Matter (DM) particles in the Milky Way’s halo could self-annihilate or decay, producing Standard Model (SM) particles such as gamma rays. These processes may generate detectable excesses in the gamma-ray energy spectra observed at Earth. We search for such signatures using a sample of data collected by the Fermi Large Area Telescope in the energy range from 1 GeV to 1 TeV energy range in...

The Pierre Auger Observatory is the world’s largest cosmic-ray detector, designed to study ultra-high-energy cosmic rays (UHECRs). A key observable for determining their mass composition is the depth of the maximum of air showers, $X_\text{max}$. Using the Fluorescence Detector (FD), $X_\text{max}$ is measured with high precision, albeit with a limited duty cycle. A recent analysis extends the...

There is a strong conflict between the huge value of vacuum energy according to theoretical estimates and the observed upper bound of its value. We propose a mechanism of the vacuum energy adjustment down to the existing observational limits via an interaction of the massless scalar field with the curvature scalar. An uncompensated remnant could possibly be identified with the observed...

The AEgIS experiment at CERN is primarily designed to investigate the gravitational interaction between matter and antimatter by measuring the free fall of antihydrogen in a field-free environment. Its core objective is to test the weak equivalence principle for antimatter using a pulsed antihydrogen beam and high-precision spatial detection. In parallel, AEgIS pursues a range of complementary...

The appearance of a dilaton in a charge-gapped phase of the three-dimensional Gross-Neveu model with time reversal violating deformation is discussed. Some implications in the context of two-dimensional Dirac materials are explored.

More than a decade ago, a Born--Infeld type tachyonic dark energy model raised considerable interest, being able to drive the evolution of the universe to the presently dark energy dominated regime. Depending on the model parameters, a six-fold evolution turned possible. Early confrontation with Supernovae Ia and Hubble parameter data disruled evolutions of type IV and V. Further, the...

Third-generation ground-based gravitational-wave detectors promise a transformative leap in sensitivity, unlocking the ability to detect signals from the Universe's earliest epochs. Meeting these ambitious goals requires overcoming numerous noise sources, both technical and fundamental, with laser frequency noise emerging as a critical challenge. Suppression of this noise must go far beyond...
