Sensitivity for four-body tau-lepton decays at Belle and Belle II experiments

Autor: Domínguez, I., Damas, P. S. Mares, Lerma, P. L. M. Podesta, Pérez, D. Rodríguez

We study the expected sensitivity at Belle and Belle II for four-body $\tau^\mp \to X^\pm l^\mp l^\mp \nu_{\tau}$ decays where $l=e$ or $\mu$ and $X=\pi$, $K$, $\rho$ and $K^*$ mesons. These decay processes violate the total lepton number ($|\Delta L

The fin whale Balaenoptera physalus is a large rorqual species occurring worldwide, mainly in temperate and subpolar zones. In contrast to many baleen whales, not all the fin whale populations show the same model of migration. In fact, migratory beha

Observation of alpha-particles in recent D–T experiments on JET

Publikováno v: Nuclear Fusion, Vol 64, Iss 8, p 086059 (2024)

The fusion reaction between deuterium and tritium, D ( T,n ) ^4 He is the main source of energy in future thermonuclear reactors. Alpha-particles ( ^4 He -ions) born with an average energy of 3.5 MeV transferring energy to the thermal plasma during t

Alpha particle loss measurements and analysis in JET DT plasmas

Publikováno v: Nuclear Fusion, Vol 64, Iss 9, p 096038 (2024)

Burning reactor plasmas will be self-heated by fusion born alpha particles from deuterium-tritium reactions. Consequently, a thorough understanding of the confinement and transport of DT-born alpha particles is necessary to maintain the plasma self-h

Publikováno v: Nuclear Materials and Energy, Vol 34, Iss , Pp 101354- (2023)

The dynamic interplay between the core and the edge plasma has important consequences in the confinement and heating of fusion plasma. The transport of the Scrape-Off-Layer (SOL) plasma imposes boundary conditions on the core plasma, and neutral tran
