A new way of comparing double beta decay experiments
M. Biassoni,O. Cremonesi,P. Gorla
Physics , 2013,
Abstract: Many experiments whose goal is the search for neutrino-less double beta decay are taking data or in a final construction stage. The need for a tool that allows for an objective comparison between the sensitivity of different experiments is mandatory in order to understand the potential of the next generation projects and focus on the best promising technologies.
CP Violation Results from B Decays at BaBar
Pietro Biassoni
Physics , 2011, DOI: 10.1088/1742-6596/335/1/012036
Abstract: In the present paper we review recent experimental results from the BaBar experiment concerning the measurement of the CKM angles. A particular highlight is given to the novel independent determination of the angle alpha from B0 -> a_1(1260)+/- pi -/+ and to the recent full-luminosity updates of several angle gamma measurements.
Recent Results in Charmonium Spectroscopy at B-factories
Pietro Biassoni
Physics , 2010,
Abstract: Charmonium spectroscopy gained renewed interest after the discovery in 2003 of the unpredicted X(3872) charmonium-like state, above the $D\overline{D}$ threshold. To date many charmonium-like states above the $D\overline{D}$ threshold have been claimed. Some of these states do not easily fit the conventional charmonium picture. In this article we review recent experimental results in this field, reported by the BaBar and Belle Collaborations.
Measurements of Time-Dependent CP Asymmetries in b\to s Penguin Dominated Hadronic B Decays at BaBar
Pietro Biassoni
Physics , 2009, DOI: 10.1063/1.3327744
Abstract: We report measurements of Time-Dependent CP asymmetries in several $b\to s$ penguin dominated hadronic B decays, where New Physics contributions may appear. We find no significant discrepancies with respect to the Standard Model expectations.
Branching fractions and charge asymmetries in charmless hadronic B decays at BABAR
Pietro Biassoni
Physics , 2009,
Abstract: We present measurements of branching fraction, polarization and charge asymmetry in charmless hadronic B decays with eta, eta', omega, and b_1 in the final state. All the results use the final BABAR dataset.
Study of Supernova ν-Nucleus Coherent Scattering Interactions
Carlos Martinez Amaya,Matteo Biassoni
Physics , 2011, DOI: 10.1016/j.astropartphys.2012.05.009
Abstract: Presently, there are several experimental setups dedicated to rare event searches, such as dark matter interactions or double beta decay, in the building or commissioning phases. These experiments often use large mass detectors and have excellent performance in terms of energy resolution, low threshold and extremely low backgrounds. In this paper we show that these setups have the possibility to exploit coherent scattering on nuclei to detect neutrinos from galactic supernova explosions, thus enlarging the number of early detection "observatories" available and helping in the collection of valuable data to perform flavour-independent studies of neutrinos' emission spectra.
Response of a TeO_2 bolometer to alpha particles
F. Bellini,M. Biassoni,C. Bucci,N. Casali,I. Dafinei,Z. Ge,P. Gorla,F. Ferroni,F. Orio,C. Tomei,M. Vignati,Y. Zhu
Physics , 2010, DOI: 10.1088/1748-0221/5/12/P12005
Abstract: $TeO_2$ crystals are used as bolometers in experiments searching for Double Beta Decay without emission of neutrinos. One of the most important issues in this extremely delicate kind of experiments is the characterization of the background. The knowledge of the response to $\alpha$ particles in the energy range where the signal is expected is therefore a must. In this paper we report the results on the response function of a $TeO_2$ bolometer to $\alpha$'s emitted by $^{147}$Sm dissolved in the crystal at the growth phase. A Quenching Factor of ($1.0076\pm 0.0005$) is found, independent of the temperature in the investigated range. The energy resolution on $\alpha$ peaks shows a standard calorimeter energy dependence: $\sigma\; [\rm{keV}] = (0.56 \pm 0.02) \oplus (0.010 \pm 0.002)\sqrt{E[\rm{keV}]} $. Signal pulses show no difference between $\alpha$ and $\beta\gamma$ particles

The 4 K outer cryostat for the CUORE experiment: construction and quality control
F. Alessandria,M. Biassoni,G. Ceruti,A. Chiarini,M. Clemenza,O. Cremonesi,V. Datskov,S. Dossena,M. Faverzani,E. Ferri,A. Nucciotti,M. Perego,E. Previtali,M. Sisti,L. Taffarello,F. Terranova
Physics , 2013, DOI: 10.1016/j.nima.2013.06.015
Abstract: The external shell of the CUORE cryostat is a large cryogen-free system designed to host the dilution refrigerator and the bolometers of the CUORE experiment in a low radioactivity environment. The three vessels that form the outer shell were produced and delivered to the Gran Sasso underground Laboratories in July 2012. In this paper, we describe the production techniques and the validation tests done at the production site in 2012.
The Future of Neutrino Mass Measurements: Terrestrial, Astrophysical, and Cosmological Measurements in the Next Decade. Highlights of the NuMass 2013 Workshop. Milano, Italy, February 4 - 7, 2013

Physics , 2013,
Abstract: The third Workshop of the NuMass series ("The Future of Neutrino Mass Measurements: Terrestrial, Astrophysical, and Cosmological Measurements in the Next Decade: NuMass 2013") was held at Dipartimento di Fisica "G. Occhialini, University of Milano-Bicocca in Milano, Italy, on 4-7 February 2013. The goal of this international workshop was to review the status and future of direct and indirect neutrino mass measurements in the laboratory as well as from astrophysical and cosmological observations. This paper collects most of the contributions presented during the Workshop.
