CP VIOLATIONS (AND MORE) AFTER THE FIRST TWO YEARS OF LHCB
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The most interesting cosmological open problems, baryon asymmetry, dark matter, inflation and dark energy, are not explained by the standard model of particle physics (SM). The finalgoal of the Large Hadron Collider an ...
SEARCH FOR DARK MATTER WITH GAMMA-RAYS: A REVIEW
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Successfully launched in June 2008, the Fermi Gamma-ray Space Telescope, formerly named GLAST, has been observing the high-energy gamma-ray sky with unprecedented sensitivity inthe 20MeV ÷ 300 GeV energy range and electrons ...
THE HISTORY OF THE S PROCESS AND ITS PRESENT STATE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
We review the history and the present status of the s-process and point to problems in need of clarification. In some cases it has to do with lack of experimental data and in other the theory is missing.
DETECTION OF A CHANGE OF SLOPE IN THE SPECTRUM OF HEAVY MASS COSMIC RAYS PRIMARIES BY THE KASCADE-GRANDE EXPERIMENT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
KASCADE-Grande is an extensive air shower experiment devoted to the study of cosmic rays in the 1016 ÷ 1018 eV energy range. The array is composed by different detectors allowing independent measurements of the number of ...
MOONLIGHT: A NEW LUNAR LASER RANGING RETROREFLECTOR INSTRUMENT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Since 1969 Lunar Laser Ranging (LLR) to the Apollo Cube Corner Reflector (CCR) arrays has supplied several significant tests of gravity: Geodetic Precession, the Strong and Weak Equivalence Principle (SEP, WEP), the ...
THE NA62 EXPERIMENT AT CERN AND THE MEASUREMENT OF THE ULTRA-RARE DECAY K⁺→π⁺ v ̄v
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The NA62 experiment at CERN aims at the very challenging task of measuring with 10% relative error the Branching Ratio of the ultra-rare decay of the K+ into π+ ν¯ν which is expected to occur only in about 8 out of 1011 ...
A COMPUTER CLUSTER SYSTEM FOR PSEUDO-PARALLEL EXECUTION OF GEANT4 SERIAL APPLICATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Simulation of the interactions between particles and matter in studies for developing X-rays detectors generally requires very long calculation times (up to several days or weeks). These times are often a serious limitation ...
TeV GAMMA RAYS: OBSERVATIONS VERSUS EXPECTATIONS & THEORY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The scope of this paper is to discuss two important questions relevant for TeV γ-ray astronomy; the pursuit to reveal the origin of cosmic rays in our galaxy, and the opacity of the universe in γ-rays. The origin of cosmic ...
THE SENSITIVITY OF THE GREENHOUSE EFFECT TO CHANGES IN THE CONCENTRATION OF GASES IN PLANETARY ATMOSPHERES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
We present a radiative transfer model for Earth-Like-Planets (ELP). The model allows the assessment of the effect of a change in the concentration of an atmospheric component, especially a greenhouse gas (GHG), on the ...
THE AUGER ENGINEERING RADIO ARRAY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The Auger Engineering Radio Array currently measures MHz radio emission from extensive air showers induced by high energy cosmic rays with 24 self-triggered radio detector stations. Its unique site, embedded into the ...
