Underlying Event Studies at CDF

We present recent studies about the `underlying event' which originates mostly from soft spectator interactions. First Run II data results are compared to published Run I results and to QCD Monte Carlo models.Comment: 7 pages, 4 figures, Presented at 11th International Workshop on Deep Inelastic Scattering (DIS 2003), St. Petersburg, Russia, 23-27 Apr 200

The CDF MiniPlug Calorimeters

Two MiniPlug calorimeters, designed to measure the energy and lateral position of particles in the (forward) pseudorapidity region of $3.6<|\eta|<5.2$ of the CDF detector, have been recently installed as part of the Run II CDF upgrade at the Tevatron $\bar pp$ collider. They consist of lead/liquid scintillator read out by wavelength shifting fibers arranged in a pixel-type towerless geometry suitable for `calorimetric tracking'. The design concept, the prototype performance and the final design of the MiniPlugs are here described. A recent cosmic ray test resulted in a light yield of approximately 100 pe/MIP, which exceeds our design requirements.Comment: 15 pages, 17 figures; contribution to DPF200

A Scintillator Tile-Fiber Preshower Detector for the CDF Central Calorimeter

The front face of the CDF central calorimeter is being equipped with a new Preshower detector, based on scintillator tiles read out by WLS fibers, in order to cope with the luminosity increase provided by the Main Injector during the Tevatron's Run II data taking. A light yield of about 40 pe/MIP at the tile exit was obtained, exceeding the design requirements.Comment: 4 pages, 8 figures.

Destroyed Places and Ancient Wars. Digital Tools for the Montecastrese Fortress

In the XX century, after being forgotten for centuries, a series of archaeological excavations have brought to light the settlement, named “Montecastrese”, a system of Medieval fortifications organized on the top of a hill near the town of Camaiore, on the Tirreno sea. The archaeologists brought back to light the traces of the fortress and of the village, exploring the monumental ruins of the northern tower, still in place and tumbled down in two main large parts. In the first half of the XIII century, the castle of Montecastrese was conquered and destroyed by the army of Lucca. At the time of its major development the small fortress was organized around two main towers, with walls and various houses. A quite extended village was placed on the southern side of the hill. In 2015 the municipality of Camaiore commissioned a complete digital survey to the Dipartimento di Architettura in Florence. The general survey plan has seen the use of aerial photogrammetric survey, 3D laser scanner survey and terrestrial photogrammetry. The use of 3D modeling of all the lost parts, from the houses to the defense walls, to the system of towers was one of the focal point in this work, using the modeling process from the survey and supporting the reconstruction hypothesis with previous archaeological data, while matching the missing parts with similar architectures and the needs of the medieval defense/attack techniques. For the northern tower a specific operation based on the use of 3D printed models was brought on to bring to an end the debate about the sequence of the fall of the tower, quite important to the digital reconstruction of this building, the direct manipulation of a scaled model turned out to be a fundamental step for the completion of this part of the research.

Ecological effects of multiple stressors on a deep lake (Lago Maggiore, Italy) integrating neo and palaeolimnological approaches

To understand interactions of lake physical characteristics, trophic dynamics and climate in Lago Maggiore, we compare longterm limnological and meteorological monitoring data and results from sediment cores. We include analyses of nutrients, pigments, diatoms and cladoceran microfossils. Over the past decades, caloric content increased. Eutrophication from the 1960s to early 1980s was followed by oligotrophication. DDTs, PCBs and Hg showed high contamination in the \u2760s, compared to point source inputs in the \u2790s. Algal biomass was predicted by total pigments and some algal specific carotenoids. Following nutrient enrichment, Chydorus sphaericus, and total abundance of cladocerans changed inversely with trophic status. Fewer large Daphnia since the late \u2780s matched an increase in with subfossil Eubosmina mucro lengths. Both were explained by the 10-fold increase in Bythotrephes longimanus from 1987 to 1993, when an increase of its mean annual population density occurred during warmer winter and springs. Bythotrephes remained abundant and further increased during the following 10 years as water temperature increased. We conclude that warmer water affects food chains indirectly by changing habitat use and predator-prey interactions. Relative abundances of Daphnia and its peak population density in the warm year of the oligotrophic period (2003) were close to the record from the mesotrophic period in 1982, supporting the hypothesis that warming can produce a eutrophication-like signal. The study illustrates the complexity of biological responses to synchronous changes in multiple drivers (e.g., eutrophication, fish introduction, ban of fish harvesting, chemical pollution, and climate) and, despite this complexity, how Lago Maggiore responded to multiple stressors

Search for Third Generation Vector Leptoquarks in p anti-p Collisions at sqrt(s) = 1.96 TeV

We describe a search for a third generation vector leptoquark (VLQ3) that decays to a b quark and tau lepton using the CDF II detector and 322 pb^(-1) of integrated luminosity from the Fermilab Tevatron. Vector leptoquarks have been proposed in many extensions of the standard model (SM). Observing a number of events in agreement with SM expectations, assuming Yang-Mills (minimal) couplings, we obtain the most stringent upper limit on the VLQ3 pair production cross section of 344 fb (493 fb) and lower limit on the VLQ3 mass of 317 GeV/c^2 (251 GeV/c^2) at 95% C.L.Comment: 7 pages, 2 figures, submitted to PR
