Nuclear Physics B - Proceedings Supplements, 1996 A brief sketch is made of the present observational status of neutrino properties, with emphasis on the hints from solar and atmospheric neutrinos, as well as cosmological data on the amplitude of primordial density fluctuations. Implications of neutrino mass in particle accelerators, astrophysics and cosmology are discussed.

A neutrino floor for the Migdal effect
Journal of High Energy PhysicsNeutrino-nucleus scatterings in the detector could induce electron ionization signatures due to the Migdal effect. We derive prospects for a future detection of the Migdal effect via coherent elastic solar neutrino-nucleus scatterings in liquid xenon ...

An unorthodox alternative for righthanded neutrinos: lefthanded see-saw [PDF]
Acta Phys.Polon. B31 (2000) 673-679, 1999 A new lefthanded see-saw mechanism is constructed, implying both the smallness of active-neutrino masses and decoupling of heavy passive neutrinos, similarly to the situation in the case of conventional see-saw. But now, in place of the conventional righthanded neutrinos, the lefthanded sterile neutrinos play the role of heavy passive neutrinos, the ...

No collective neutrino flavor conversions during the supernova accretion phase
, 2011 The large neutrino fluxes emitted with a distinct flavor hierarchy from core-collapse supernovae (SNe) during the post-bounce accretion phase, offer the best opportunity to detect effects from neutrino flavor oscillations. We perform a dedicated study of

Flavor in SU(5)$SU(5)$ Finite Grand Unified Models
Fortschritte der Physik, Volume 72, Issue 12, December 2024.Abstract Four SU(5)N=1$SU(5) \nobreakspace N=1$ supersymmetric models which exhibit S3$S_3$ and/or ZN$Z_N$ symmetries are studied, that are finite to two or all loops, and their corresponding mass matrices. The first is an all‐loop finite model based on an S3×Z3×Z2$S_3\times Z_3\times Z_2$ flavor symmetry, which leads to phenomenologically nonviable ...

Compreendendo a oscilação dos neutrinos
Revista Brasileira de Ensino de FísicaEste trabalho é uma introdução ao modelo da oscilação de neutrinos para estudantes de física. Apresentamos o modelo de mistura de neutrinos baseado no conceito de superposição de estados. Em particular, consideraremos o caso onde os neutrinos se propagam

Neutrino-neutrino and neutrino-matter helicity flip interactions [PDF]
arXiv, 2001 Taking into account that neutrinos are massive particles and that they are produced mainly as states of negative helicity, we show that the neutral and charged current interactions change these neutrinos into transversally polarized states. This implies a considerable reduction of the neutrino flux when propagating through ordinary matter (electrons ...

Effect of Coulomb collisions on time variations of the solar neutrino flux
, 1999 We consider the possibility of time variations of the solar neutrino flux due to the radial motion of the Earth and neutrino interference effects. We calculate the time variations of the detected neutrino flux and the extent to which they are suppressed ...

Pediatric Blood &Cancer, Volume 71, Issue 11, November 2024.Abstract An attractive flower from the island of Madagascar has in part saved the lives of thousands of children with acute lymphoblastic leukemia (ALL). Random mutations and alterations to the genome led to the evolution of genes encoding enzymes, which would provide the periwinkle flower an arsenal of secondary metabolites to survive within the ...
