Half-life Expectations for Neutrinoless Double Beta Decay in Standard and Non-Standard Scenarios
We investigate the half-life expectations for neutrinoless double beta decay
by applying statistical distributions of neutrino mixing observables, neutrino
mass constraints from cosmology and nuclear matrix elements. The analysis is
performed in the standard scenario of active Majorana neutrino exchange, when
light sterile neutrinos are added, and within TeV-scale left-right symmetric
frameworks. The latter two cases correspond to a modified phenomenology of
double beta decay for a normal and inverted mass ordering, and thus different
discovery potential for future experiments.Comment: 18 pages, 10 figures, and 4 table
Study on space-time structure of Higgs boson decay using HBT correlation Method in ee collision at =250 GeV
The space-time structure of the Higgs boson decay are carefully studied with
the HBT correlation method using ee collision events produced through
Monte Carlo generator PYTHIA 8.2 at =250GeV. The Higgs boson jets
(Higgs-jets) are identified by H-tag tracing. The measurement of the Higgs
boson radius and decay lifetime are derived from HBT correlation of its decay
final state pions inside Higgs-jets in the ee collisions events with an
upper bound of fm and fs. This result is consistent with CMS data.Comment: 7 pages,3 figure
