Search for a Low-Mass Scalar Higgs Boson Decaying to a Tau Pair in Single-Photon Decays of Upsilon(1S)
J. P. Lees, others
We search for a low-mass scalar CP-odd Higgs boson, A0, produced in the radiative decay of the Upsilon resonance and decaying into a tau+tau- pair: Upsilon(1S)->gamma A0. The produ…
Search for 14.4 keV solar axions from M1 transition of Fe-57 with CUORE crystals
The Cuore Collaboration, F. Alessandria, R. Ardito +112
We report the results of a search for axions from the 14.4 keV M1 transition from Fe-57 in the core of the sun using the axio-electric effect in TeO2 bolometers. The detectors are…
Dependence of the energy resolution of a scintillating crystal on the readout integration time
V. Bocci, D. Chao, G. Chiodi +7
The possibilty of performing high-rate calorimetry with a slow scintillator crystal is studied. In this experimental situation, to avoid pulse pile-up, it can be necessary to base…
The branching fraction of tau --> pi- K0S K0S (pi0) nu decays
J. P. Lees
We present a study of tau- --> pi- K0S K0S (pi0) nu and tau- --> K- K0S K0S (pi0) nu decays using a dataset of 430 million tau lepton pairs, corresponding to an integrated luminosi…
Precision Measurement of the B to X_s γPhoton Energy Spectrum, Branching Fraction, and Direct CP Asymmetry A_{CP}(B to X_{s+d}γ
The BaBar Collaboration
The photon spectrum in the inclusive electromagnetic radiative decays of the meson, plus , is studied using a data sample of $(382.8 \pm 4.2) \ti…
Search for resonances decaying to eta_c pi+ pi- in two-photon interactions
The BABAR Collaboration, J. P. Lees, others
We report a study of the process gamma gamma -> X -> eta_c pi+ pi-, where X stands for one of the resonances chi_{c2}(1P), eta_c(2S), X(3872), X(3915), or chi_{c2}(2P). The analysi…
Evidence for an excess of B -> D(*) Tau Nu decays
The BaBar Collaboration
Based on the full BaBar data sample, we report improved measurements of the ratios R(D(*)) = B(B -> D(*) Tau Nu)/B(B -> D(*) l Nu), where l is either e or mu. These ratios are sens…
Study of the reaction e^{+}e^{-} -->J/psiπ^{+}π^{-} via initial-state radiation at BaBar
The BABAR Collaboration
We study the process with initial-state-radiation events produced at the PEP-II asymmetric-energy collider. The data were recorded with the BaBar detector…
Measurement of Branching Fractions and Rate Asymmetries in the Rare Decays B -> K(*) l+ l-
The BABAR Collaboration
In a sample of 471 million BB events collected with the BABAR detector at the PEP-II e+e- collider we study the rare decays B -> K(*) l+ l-, where l+ l- is either e+e- or mu+mu-. W…
On the Spin of the X(3872)
R. Faccini, F. Piccinini, A. Pilloni +1
Whether the much studied X(3872) is an axial or tensor resonance makes an important difference to its interpretation. A recent paper by the BaBar collaboration raised the viable hy…
Charged particle's flux measurement from PMMA irradiated by 80 MeV/u carbon ion beam
C. Agodi, G. Battistoni, F. Bellini +22
Hadrontherapy is an emerging technique in cancer therapy that uses beams of charged particles. To meet the improved capability of hadrontherapy in matching the dose release with th…
Study of the time and space distribution of beta+ emitters from 80 MeV/u carbon ion beam irradiation on PMMA
C. Agodi, F. Bellini, G. A. P. Cirrone +19
Proton and carbon ion therapy is an emerging technique used for the treatment of solid cancers. The monitoring of the dose delivered during such treatments and the on-line knowledg…
