Predicted charged charmonium-like structures in the hidden-charm dipion decay of higher charmonia
charged charmonium-like dipion decay
2011/7/21
In this work, we predict two charged charmonium-like structures close to the $D^\ast\bar{D}$ and $D^\ast\bar{D}^\ast$ thresholds, where the Initial Single Pion Emission mechanism is introduced in the ...
Neutrino-less Double Beta Decay and Particle Physics
Neutrino-less Double Beta Decay Particle Physics
2011/7/21
We review the particle physics aspects of neutrino-less double beta decay. This process can be mediated by light massive Majorana neutrinos (standard interpretation) or by something else (non-standard...
Uncertainties in nuclear transition matrix elements for neutrinoless $ββ$ decay II: the heavy Majorana neutrino mass mechanism
matrix elements neutrino mass mechanism
2011/7/20
Employing four different parametrization of the pairing plus multipolar type of effective two-body interaction and three different parametrizations of Jastrow-type of short range correlations, the unc...
Spectral distribution method for neutrinoless double-beta decay nuclear transition matrix elements: Binary correlation results
neutrinoless double-beta decay nuclear transition
2011/7/20
Neutrinoless double-beta decay nuclear transition matrix elements are generated by an effective two-body transition operator and it consists of Gamow-Teller like and Fermi like (also tensor) operators...
Analysis of Experiments Exhibiting Time-Varying Nuclear Decay Rates: Systematic Effects or New Physics?
Exhibiting Time-Varying Nuclear Decay Rates Systematic Effects
2011/7/20
Since the 1930s, and with very few exceptions, it has been assumed that the process of radioactive decay is a random process, unaffected by the environment in which the decaying nucleus resides. There...
Concerning the Phases of Annual Variations of Nuclear Decay Rates
Annual Variations Nuclear Decay Rates
2011/7/21
Recent analyses of datasets acquired at the Brookhaven National Laboratory and at the Physikalisch-Technische Bundesanstalt both show evidence of pronounced annual variations, suggestive of a solar in...
Evidence for Time-Varying Nuclear Decay Rates: Experimental Results and Their Implications for New Physics
Time-Varying Nuclear Decay Rates New Physics
2011/7/20
Unexplained annual variations in nuclear decay rates have been reported in recent years by a number of groups. We show that data from these experiments exhibit not only variations in time related to E...

Search for beta plus/EC double beta decay of 120Te
Search beta plus/EC double beta decay 120Te
2010/12/29
We present a search for beta plus/EC double beta decay of 120Te performed with the CUORICINO experiment, an array of TeO2 cryogenic bolometers. After collecting 0.0573 kg y of 120Te, we see no evidenc...
Azimuthal correlations of electrons from heavy-flavor decay with hadrons in p+p and Au+Au collisions at sqrt(s_NN)=200 GeV
Azimuthal correlations electrons heavy-flavor decay with hadrons p+p and Au+Au collisions sqrt(s_NN)=200 GeV
2011/1/4
Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary scaled p+p collisions. These mea...
Density-dependent nuclear interactions and the beta decay of 14C: chiral three-nucleon forces and Brown-Rho scaling
Effective field theory at finite density chiral three-nucleon force Brown-Rho scaling
2011/1/7
We study the role of density-dependent low-momentum nucleon-nucleon interactions in describing the anomalously long beta decay lifetime of 14C. We approach this problem both from the perspective of ch...

We report on the recent results of searches for lepton-flavor-violating t decays as well as leptonnumber-violating B decays with the world-highest data samples accumulated at the Belle.
Neutrino masses and Neutrinoless Double Beta Decay: Status and expectations
Neutrino masses double beta decay
2010/3/15
Two most outstanding questions are puzzling the world of neutrino Physics: the possible Majorana nature of neutrinos and their absolute mass scale. Direct neutrino mass measurements and neutrinoless d...
Relativistic studies of the decay constants of S wave and P wave mesons

2010/1/18
Relativistic corrections are important in hadronic physics since even for the heavy hadrons there are sizable relativistic corrections. Therefore one should use a relativistic model to describe the hi...
