Top Quark Measurements at the Fermilab Tevatron

The top quark, discovered at the Tevatron in 1995, is a very interesting particle. Precise measurement of the top properties using large data samples will allow stringent tests of the Standard Model and offer a unique window on new physics. In this report will be reviewed the status of the current knowledge of the top quark as provided by the Run I results of the CDF and D0 experiment. A first look at various preliminary measurements obtained with data collected during Run II will be also presented.Comment: 10 pages, 14 figures Proceeding of Lepton-Photon 2003, Fermilab Batavia (IL), August 200

First look at the physics case of TLEP

The discovery by the ATLAS and CMS experiments of a new boson with mass around 125 GeV and with measured properties compatible with those of a Standard-Model Higgs boson, coupled with the absence of discoveries of phenomena beyond the Standard Model at the TeV scale, has triggered interest in ideas for future Higgs factories. A new circular e+e− collider hosted in a 80 to 100km tunnel, TLEP, is among the most attractive solutions proposed so far. It has a clean experimental environment, produces high luminosity for top-quark, Higgs boson, Wand Z studies, accommodates multiple detectors, and can reach energies up to the t¯t threshold and beyond. It will enable measurements of the Higgs boson properties and of Electroweak Symmetry-Breaking (EWSB) parameters with unequalled precision, offering exploration of physics beyond the Standard Model in the multi-TeV range. Moreover, being the natural precursor of the VHE-LHC, a 100TeV hadron machine in the same tunnel, it builds up a long-term vision for particle physics

Comments on "Wall-plug (AC) power consumption of a very high energy e+/e- storage ring collider" by Marc Ross

The paper arXiv:1308.0735 questions some of the technical assumptions made by the TLEP Steering Group when estimating in arXiv:1305.6498 the power requirement for the very high energy e+e- storage ring collider TLEP. We show that our assumptions are based solidly on CERN experience with LEP and the LHC, as well accelerators elsewhere, and confirm our earlier baseline estimate of the TLEP power consumption.Comment: 6 page

Additive Manufacturing and Spare Parts: Literature Review and Future Perspectives

The use of Additive Manufacturing (AM) for spare parts management has increasingly gained interest in the last years, thanks to the possibility provided by AM technologies to print-on-demand. In such a way, the high spare parts inventory level necessary with Conventional Manufacturing (CM) techniques could be reduced due to a faster responsiveness of AM. Recently, some researchers have investigated the profitability of the transition from CM to AM for the spare parts management, and these contributions are herein reviewed, highlighting the main novelties and limitations of these studies. Based on the output of the literature review and on interviews with experts and industrial partners, future research perspectives have been reported. Four main research areas have been identified, and a multidisciplinary approach is suggested to accomplish them all.submittedVersio

d-α-Tocopherol inhibits low density lipoprotein induced proliferation and protein kinase C activity in vascular smooth muscle cells

AbstractNative and malondialdehyde modified low density lipoproteins have been shown to stimulate smooth muscle cell proliferation (A7r5) in vitro. The stimulation is associated with an increase of protein kinase C activity. d-α-Tocopherol, at physiological concentrations, has been found to inhibit both protein kinase C activity and cell proliferation

Unifying gauge couplings at the string scale

Using the current precision electroweak data, we look for the minimal particle content which is necessary to add to the standard model in order to have a complete unification of gauge couplings and gravity at the weakly coupled heterotic string scale. We find that the addition of a vector-like fermion at an intermediate scale and a non-standard hypercharge normalization are in general sufficient to achieve this goal at two-loop level. Requiring the extra matter scale to be below the TeV scale, it is found that the addition of three vector-like fermion doublets with a mass around 700 GeV yields a perfect string-scale unification, provided that the affine levels are $(k_Y, k_2 ,k_3)=(13/3, 1, 2)$, as in the $SU(5) \times SU(5)$ string-GUT. Furthermore, if supersymmetry is broken at the unification scale, the Higgs mass is predicted in the range 125 GeV - 170 GeV, depending on the precise values of the top quark mass and $\tan \beta$ parameter.Comment: 11 pages, 4 eps figures, using jpconf style, talk given at CORFU2005, RTN meeting ``The Quest for Unification: Theory Confronts Experiment'', 11 - 18 September 2005, Corfu, Greec

Search for new phenomena with the CDF detector

We present the results of the searches for new phenomena in pp collisions at {radical}s=1.8 TeV with the CDF detector using the full data sample of 110 pb{sup -1} collected between 1992 and 1995. We have searched for new physics in events with two photons, testing some of the hypotheses proposed to explain the appearance of the CDF ee{gamma}{gamma} E{sub T} event. New results on the search for a heavy neutral scalar object, charged Higgs bosons (H{sup {+-}}) and the scalar top quark are presented. Finally we summarize the CDF results on the search for third generation leptoquarks
