IceCube search for dark matter annihilation in nearby galaxies and galaxy clusters

Matthias Wolf, Shirit Cohen, Sofia Vallecorsa, Mathieu Ribordy, Xiaoxia Bai

We present the results of a first search for self-annihilating dark matter in nearby galaxies and galaxy clusters using a sample of high-energy neutrinos acquired in 339.8 days of live time during 2009/10 with the IceCube neutrino observatory in its 59-str ...

An experiment to test advanced materials impacted by intense proton pulses at CERN HiRadMat facility

Nikolaos Charitonidis, Francesco Cerutti, Alessandro Masi

Predicting the consequences of highly energetic particle beams impacting protection devices as collimators or high power target stations is a fundamental issue in the design of state-of-the-art facilities for high-energy particle physics. These complex dyn ...

A FEASIBILITY EXPERIMENT OF A W-POWDER TARGET IN THE HIRADMAT FACILITY AT CERN

Leonid Rivkin, Nikolaos Charitonidis

Granular solid targets made of fluidized tungsten powder or a static pebble bed of tungsten spheres, have been proposed and are being studied as an alternative configuration for high-power (>1MW of beam power) target systems, suitable for a future Super Be ...

Development of the Electromagnetic Calorimeter for the Precise Measurement of the Cosmic Ray Positron Fraction with PEBS

Lesya Shchutska

Since almost a century ago, it is known that a quarter of the energy density in the Universe is represented by the dark matter which has been seen only through gravitational interaction. Despite of intensive searches for a dark matter constituent in differ ...

Higgs boson mass and new physics

We discuss the lower Higgs boson mass bounds which come from the absolute stability of the Standard Model (SM) vacuum and from the Higgs inflation, as well as the prediction of the Higgs boson mass coming from the asymptotic safety of the SM. We account fo ...

Radiological assessment of the Collimator Materials tests at HiRadMat in 2012

Nikolaos Charitonidis

A test for several collimator materials is planned to be performed in the HiRadMat facility of CERN/SPS. Before these samples can be brought to a surface laboratory for analysis after the irradiation, a certain cool-down period has to be respected in order ...

Search for GeV-Scale Sterile Neutrinos Responsible for Active Neutrino Oscillations and Baryon Asymmetry of the Universe

Standard Model fails to explain neutrino oscillations, dark matter, and baryon asymmetry of the Universe. All these problems can be solved with three sterile neutrinos added to SM. Quite remarkably, if sterile neutrino masses are well below the electroweak ...

Impact of high energy high intensity proton beams on targets: Case studies for Super Proton Synchrotron and Large Hadron Collider

Juan Blanco Sancho, Rudiger Schmidt

The Large Hadron Collider (LHC) is designed to collide two proton beams with unprecedented particle energy of 7 TeV. Each beam comprises 2808 bunches and the separation between two neighboring bunches is 25 ns. The energy stored in each beam is 362 MJ, suf ...

Experimental proposal Test of radiation protection instrumentation in HiRadMat

Nikolaos Charitonidis, Marco Silari

The knowledge of the response of radiation protection detectors in pulsed fields is very important, since this is a typical condition often encountered with stray radiation fields around particle accelerators at CERN and elsewhere. This document presents a ...

Modelling the interaction of electron clouds and microwaves

Michael Mattes, Francisco Edén Sorolla Rosario, Frank Zimmermann

This paper deals with the interaction of electron clouds with microwaves inside beam-pipes like the one of the LHC in CERN. The details of the model and recent results are presented during the conference. ...
