The renormalization-group running of neutrino mixing is undetectable
Gabriela Barenboim, Mauricio Bustamante, Qinrui Liu
Quantum corrections make the parameters of a theory depend on an arbitrary renormalization scale, . The renormalization-group (RG) running of neutrino masses and mixing is a sta…
Measurement of the neutrino cross section across the TeV scale using IceCube data
Rasmi Hajjar, Mauricio Bustamante, Sergio Palomares-Ruiz
Neutrinos interact with matter exclusively through the weak force, resulting in extremely small cross sections that are difficult to measure. At TeV energies, neutrino-nucleon inte…
Magnus: neutrino oscillation probabilities for any Hermitian Hamiltonian, any number of flavors, and any matter profile
Mauricio Bustamante
Interpreting neutrino oscillation measurements requires computing the probability that a neutrino born with one flavor is detected with another. In vacuum and in matter of constant…
NASA ASTRA Initiative White Paper: Space-Based Mission for Ultrahigh Energy Particles
Mauricio Bustamante, Johannes Eser, Ke Fang +9
Ultra-high-energy cosmic rays ( EeV) are the highest-energy particles known, signaling extreme particle processes at work in the universe. However, many aspec…
Electron stability constrains neutrino time delays
Mauricio Bustamante, José Manuel Carmona, José Luis Cortés +2
Superluminal neutrino propagation, induced by Lorentz-invariance violation (LIV), is strongly constrained by vacuum pair emission, , a process ordinarily forbidd…
Are neutrinos Majorana? Fixed-target and high-energy astrophysical searches decide
Gabriela Barenboim, Mauricio Bustamante, Qinrui Liu
Determining whether the neutrino is a Dirac or Majorana fermion remains a fundamental open question. Conventional searches rely on neutrinoless double beta decay, but this electron…
Astrophysical bounds on the high-energy evolution of neutrino mixing
Mauricio Bustamante, Qinrui Liu, Gabriela Barenboim
While conventional oscillation experiments measure neutrino mixing parameters with high precision, these measurements are strictly confined to sub-TeV scales. At higher energies, r…
Measuring neutrino mixing above 1 TeV with astrophysical neutrinos
Mauricio Bustamante, Qinrui Liu, Gabriela Barenboim
We assess the potential for measuring neutrino mixing parameters at energies above 1~TeV, for the first time, using the flavor composition of TeV--PeV astrophysical neutrinos, i.e.…
No Flavor Anisotropy in the High-Energy Neutrino Sky Upholds Lorentz Invariance
Bernanda Telalovic, Mauricio Bustamante
Discovering Lorentz-invariance violation (LIV) would upend the foundations of modern physics. Because LIV effects grow with energy, high-energy astrophysical neutrinos provide the…
A plethora of long-range neutrino interactions probed by DUNE and T2HK
Sanjib Kumar Agarwalla, Mauricio Bustamante, Masoom Singh +1
The next-generation neutrino oscillation experiments would be sensitive to the new neutrino interactions that would strengthen the search for physics beyond the Standard Model. In…
Constraints on flavor-dependent long-range interactions of high-energy astrophysical neutrinos
Sanjib Kumar Agarwalla, Mauricio Bustamante, Sudipta Das +1
Astrophysical neutrinos with energy in the TeV-PeV range traverse megaparsecs (Mpc) to gigaparsecs (Gpc) scale distances before they reach the Earth. Tiny physics effects that get…
Flavor-Dependent Long-Range Neutrino Interactions in DUNE and T2HK: Synergy Breeds Power
Masoom Singh, Mauricio Bustamante, Sanjib Kumar Agarwalla
Discovering new neutrino interactions would provide evidence of physics beyond the Standard Model. We focus on flavor-dependent long-range neutrino interactions mediated by ultra-l…
Probing Lorentz invariance with a high-energy neutrino flare
Mauricio Bustamante, John Ellis, Rostislav Konoplich +1
Time-of-flight measurements of high-energy astrophysical neutrinos can be used to probe Lorentz invariance, a pillar of modern physics. If Lorentz-invariance violation (LIV) occurs…
The next galactic supernova can uncover mass and couplings of particles decaying to neutrinos
Bernanda Telalovic, Damiano F. G. Fiorillo, Pablo Martínez-Miravé +2
Many particles predicted by extensions of the Standard Model feature interactions with neutrinos, e.g., Majoron-like bosons . If the mass of is larger than about 10 keV, the…
New limits on neutrino decay from high-energy astrophysical neutrinos
Victor B. Valera, Damiano F. G. Fiorillo, Ivan Esteban +1
Since neutrinos have mass differences, they could decay into one another. But their lifetimes are likely long, even when shortened by new physics, so decay likely impacts neutrinos…
A plethora of long-range neutrino interactions probed by DUNE and T2HK
Sanjib Kumar Agarwalla, Mauricio Bustamante, Masoom Singh +1
Upcoming neutrino experiments will soon search for new neutrino interactions more thoroughly than ever before, boosting the prospects of extending the Standard Model. In anticipati…
