The long-existing problem of neutrino mass and mixing can be connected to cosmological phenomena, such as the leptogenesis and the existence of dark matter (DM).

The neutrino mass ordering (NMO) is one of the last unmeasured fundamental parameters in the neutrino sector of the Standard Model of Particle Physics. NMO studies aim to answer the question of whether the neutrino mass ordering is normal (m3>m2>m1) or inverted (m2>m1>m3). IceCube is an ice-Cherenkov neutrino detector deployed greater than 1.5 kilometers below the surface of the South Pole....

The neutrino mass ordering (NMO) is one of the big open questions in neutrino physics. It can either be normal (m1<m2<m3) or inverted (m3<m1<m2). One way to determine the NMO is to study atmospheric neutrino oscillations. Below about 15 GeV, matter effects distort the oscillation probabilities for neutrinos (normal ordering) and anti-neutrinos (inverted ordering) while they traverse Earth's...

The phenomenon of neutrino oscillations emerges due to coherent superposition of neutrino mass states.

A high-temperature core called a proto-neutron star(PNS) is formed after a core-collapse supernova explosion. The PNS cools down by emitting neutrinos and becomes neutron-rich. It is important to understand neutrino emission of the cooling phase because it only depends on the environment of PNS, such as density, temperature, and composition. It would have smaller uncertainties than the earlier...

The origin of the relatively high solar system abundances of certain proton-rich isotopes in the $90 < A < 100$ mass range has been an enduring mystery in nuclear astrophysics. An attractive proposal to solve this problem is called the $\nu p$-process.

T-violation in neutrino oscillations in vacuum is a well known fact. Due to the CPT theorem this fact is strictly connected with the CP violating phase in the neutrino mixing matrix. Since neutrino interaction with matter or external electromagnetic field violates Lorentz invariance, the influence of external conditions can lead to T violation even in the model with real mixing matrix, e.g. in...

Based on our paper (arXiv:2201.06733) we discuss the prospects to take a picture of an extended neutrino source, i.e., resolving its angular luminosity distribution. This is challenging since neutrino directions cannot be directly measured but only estimated from the directions of charged particles they interact with in the detector material. This leads to an intrinsic blurring effect. We...

CHANDLER is an antineutrino detection technology based on a 3D segmented lattice of plastic scintillating cubes to enable surface-level deployment. Our prototype detector, MiniCHANDLER, observed an antineutrino signal via inverse beta decay at 5.5$\sigma$ significance with no overburden and minimal shielding. In this poster, we will discuss upgrades to the MiniCHANDLER detector and look at...

The Deep Underground Neutrino Experiment (DUNE) is an international collaboration focused on studying neutrino oscillation over a long baseline (1300 km). DUNE will make use of near and far detectors based on the LArTPC (Liquid Argon Time Projection Chamber) technology. The far detector site will be located 1.5 km underground at the Sanford Underground Research Facility in Lead, South Dakota....

The next core-collapse supernova (CCSN) in the Milky Way presents a once-in-a-lifetime opportunity to obtain detailed measurements on the explosion of a star and the extreme conditions found within its core. Local CCSNe are exceedingly rare, so it is critical that as much information is captured from the event as is possible. The high-intensity neutrino burst from a CCSN, which may arrive at...

T2K (Tokai to Kamioka) is a long baseline neutrino oscillation experiment
Go to contribution page
that uses a pure, νμ or ¯νμ flux from the J-PARC accelerator,
sharply peaked around 0.6 GeV with the aim to precisely measure the
sin2 θ23, and Δm^2_{32} oscillation parameters as well as the CP-violating
phase factor, δCP . Within the latest analysis stages, many improvements
have been made to the T2K oscillation... -
The Jiangmen Underground Neutrino Observatory (JUNO) uses a 20 kton liquid scintillator detector to capture medium-baseline reactor neutrinos to measure the neutrino mass ordering. Event reconstruction is one of the key challenges in reaching the designed energy resolution of 3%/sqrt(E (MeV)). This poster presents a data-driven method to obtain the expected photo-electron distribution of...

HQE MCP-PMTs from NNVT manifest a long tail in the charge distribution. The tail component influences the estimated number of real PEs and energy resolution. In this work we tested several 8 inch MCP-PMTs to characterize the charge distributions. Gaussian mixture distribution is applied to model the charge distribution with long tail component. The parameterized charge model is used to...

The Taishan Antineutrino Observatory (JUNO-TAO) is a satellite experiment of the Jiangmen Underground Neutrino Observatory (JUNO). The main purpose of TAO experiment is to provide a precise reference spectrum for JUNO and benchmark measurement for nuclear database. TAO detector consists of a Central Detector (CD), an outer shielding and veto system. The CD will be placed at ∼30 m from a core...

With the final aim of proving the Majorana nature of neutrinos, the NEXT collaboration searches for the neutrino-less double beta decay (ββ0ν) of 136Xe with a gaseous Time Projection Chamber (TPC). The latest stage within the NEXT programme comprised the NEXT-White detector. It was the first large-scale prototype of a high-pressure Xenon gas electroluminescent TPC, and operated at the LSC from...

Multi-wavelength observations of different core-collapse Supernovae (SNe) have confirmed the presence of dense Circumstellar Material (CSM) around the progenitor star. The CSM is formed as a result of high mass loss of the progenitor star a few years prior to its death. Interaction of this CSM with high energy particles created in supernova explosion can produce secondary particles like high...

The MicroBooNE detector is a liquid argon time projection chamber (LArTPC)
Go to contribution page
with an 85 ton active mass that receives flux from the Booster Neutrino and the Neutrinos Main Injector (NuMI) beams, providing excellent spatial resolution of the reconstructed final state particles. Since 2015 MicroBooNE has accumulated many neutrino and anti-neutrino scatterings with argon nuclei enabling searches...
