We investigate whether the Minimal Supersymmetric Standard Model with the scalar masses of the third generation distinct from the first two, in order to be able to accommodate the muon anomalous magnetic moment, is consistent with the latest results from LHCb, direct collider bounds from ATLAS and CMS. In particular, we show that this class of models allows for satisfying both the constraints f...

New data on the electron/muon ratio measured by the KASCADE extensive air shower experiment are presented. This ratio has been proven to be an important parameter for the determination of the mass of the primary particle. The electron and muon detector responses and reconstruction accuracies of the shower parameters have been studied in detailed simulations. Due to the extended lateral distribu...

We report on the development and performance of a novel track-finding processor for the Level-1 trigger of the CMS endcap muon system. The processor links track segments identified in the cathode-strip chambers of the endcap muon system into complete threedimensional tracks. It then measures the momentum of the best track candidates from the sagitta measured between three muon chambers in the e...

The role of Horizontal Showers induced by cosmic rays is discussed in detail. A new approach to the calculation of the muon component in horizontal air showers induced by protons, heavier nuclei or photons is presented which allows a simple analytical evaluation of the muon density profiles at ground level. The results of the first application of these results to horizontal air showers detected...

The spin dynamics of geometrically frustrated pyrochlore antiferromagnets Y2Mo2O7 and Tb2Mo2O7 have been investigated using muon spin relaxation. A dramatic slowing down of the moment fluctuations occurs as one approaches the spin freezing temperatures (TF522 and 25 K, respectively! from above. Below TF there is a disordered magnetic state similar to that found in a spin glass but with a residu...

The muon tomography technique, based on the multiple Coulomb scattering of cosmic ray muons, has been proposed recently as a tool to perform non-destructive assays of large volume objects without any radiation hazard. In this paper we describe the algorithms used and we show the experimental results obtained with a scanning system prototype, assembled using two large area CMS Muon Barrel drift ...

The use of a liquid metal jet [1] as the primary target at a muon collider source is not yet an established technique. Among possible alternatives, we are investigating the use of a jet of tungsten powder. We first considered metal-powder slurries, based on the example of a commercial zinc paint with density 3 g/cm. For a muon collider target, both high atomic number and high density are desira...

Since 1950’s there has been a growing interest of understanding the effects of cosmic ray radiation on the increase in average global temperature. Recent studies showed that galactic cosmic rays play a significant role in the formation of low cloud coverage and its consequent impact on the global temperature variation of the earth. A long-term measurement of the cosmic ray flux distribution at ...
