Title | Search for quark contact interactions in dijet angular distributions in pp collisions at sqrt(s)=7 TeV measured with the ATLAS detector | Type | Journal Article | ||
Year | 2011 | Publication | Physics Letters B | Abbreviated Journal | Phys. Lett. B |

Keywords | ATLAS; LHC; 7 TeV; Dijets angular distributions; Quark compositeness; Contact interactions | ||||
Abstract | Dijet angular distributions from the first LHC pp collisions at center-of-mass energy root s = 7 TeV have been measured with the ATLAS detector. The dataset used for this analysis represents an integrated luminosity of 3.1 pb(-1). Dijet chi distributions and centrality ratios have been measured up to dijet masses of 2.8 TeV, and found to be in good agreement with Standard Model predictions. Analysis of the chi distributions excludes quark contact interactions with a compositeness scale Lambda below 3.4 TeV, at 95% confidence level, significantly exceeding previous limits. | ||||

Title | Status and implications of neutrino masses: a brief panorama | Type | Journal Article | ||
Year | 2015 | Publication | International Journal of Modern Physics A | Abbreviated Journal | Int. J. Mod. Phys. A |
Volume | 30 | Issue | 13 | Pages | 1530034 - 13pp |
Keywords | Neutrino mixing and oscillations; seesaw mechanism; quark-lepton unification; flavor symmetry; electroweak symmetry breaking; neutrinoless double beta decay; dark matter; inflation | ||||
Abstract | With the historic discovery of the Higgs boson our picutre of particle physics would have been complete were it nor for the neutrino sector and cosmology. I briefly discuss the role of neutrino masses and mixing upon gauge coupling unification, electroweak breaking and the flavor sector. Time is ripe for new discoveries such as leptonic CP violation, charged lepton flavor violation and neutrinoless double beta decay. Neutrinos could also play a role is elucidating the nature of dark matter and cosmic inflation. | ||||

Title | A dead-time-free data acquisition system for prompt gamma-ray measurements during proton therapy treatments | Type | Journal Article | ||
Year | 2022 | Publication | Nuclear Instruments & Methods in Physics Research A | Abbreviated Journal | Nucl. Instrum. Methods Phys. Res. A |
Volume | 1033 | Issue | Pages | 166701 - 9pp | |
Keywords | Data acquisition; Dead time; Pile-up; Digital signal processing | ||||
Abstract | In cancer patients undergoing proton therapy, a very intense secondary radiation is produced during the treatment, which lasts around one minute. About one billion prompt gamma-rays are emitted per second, and their detection with fast scintillation detectors is useful for monitoring a correct beam delivery. To cope with the expected count rate and pile-up, as well as the scarce statistics due to the short treatment duration, we developed an eidetic data acquisition system capable of continuously digitizing the detector signal with a high sampling rate and without any dead time. By streaming the fully unprocessed waveforms to the computer, complex pile-up decomposition algorithms can be applied and optimized offline. We describe the data acquisition architecture and the multiple experimental tests designed to verify the sustained data throughput speed and the absence of dead time. While the system is tailored for the proton therapy environment, the methodology can be deployed in any other field requiring the recording of raw waveforms at high sampling rates with zero dead time. | ||||
