Direct Dark Matter searches are nowadays one of the most fervid research topics with many experimental efforts devoted to the search for nuclear recoils induced by the scattering of Weakly Interactive Massive Particles (WIMPs). Detectors able to reconstruct the direction of the nucleus recoiling against the scattering WIMP are opening a new frontier to possibly extend Dark Matter searches beyond the neutrino background. Exploiting directionality would also prove the galactic origin of Dark Matter with an unambiguous signal-to-background separation. Indeed, the angular distribution of recoiled nuclei is centered around the direction of the Cygnus constellation, while the background distribution is expected to be isotropic. Current directional experiments are based on gas TPC whose sensitivity is limited by the small achievable detector mass. In this paper we present the discovery potential of a directional experiment based on the use of a solid target made of newly developed nuclear emulsions and of optical read-out systems reaching unprecedented nanometric resolution.

Discovery potential for directional dark matter detection with nuclear emulsions
Güler, Ali Murat (2017-02-25)
Direct Dark Matter searches are nowadays one of the most exciting research topics. Several Experimental efforts are concentrated on the development, construction, and operation of detectors looking for the scattering of target nuclei with Weakly Interactive Massive Particles (WIMPs). In this field a new frontier can be opened by directional detectors able to reconstruct the direction of the WIMP-recoiled nucleus thus allowing to extend dark matter searches beyond the neutrino floor. Exploiting directionalit...
Observation of a new boson with mass near 125 GeV in pp collisions at root s=7 and 8 TeV
Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2013-06-01)
A detailed description is reported of the analysis used by the CMS Collaboration in the search for the standard model Higgs boson in pp collisions at the LHC, which led to the observation of a new boson. The data sample corresponds to integrated luminosities up to 5.1 fb(-1) at root s = 7 TeV, and up to 5.3 fb(-1) at root s = 8 TeV. The results for five Higgs boson decay modes gamma gamma, ZZ, WW, tau tau, and bb, which show a combined local significance of 5 standard deviations near 125 GeV, are reviewed. ...
Experimental Characterization of Micro Vortex Generators in Low Speed Flows
Akpolat, Tuğrul; Abdulrahim, Anas; Hassanein, Abdelrahman; Uzol, Oğuz; Perçin, Mustafa (2021-09-08)
In this study, we present the experimental results of the characterization of micro-ramp type Micro Vortex Generators (MVGs) in low-speed flows. The undisturbed boundary layer profile was measured by means of Hot-Wire Anemometry. Two MVGs with the same design but different height-to-boundary layer thickness ratios are used in this study. Two-dimensional twocomponent particle image velocimetry measurements are conducted in the wake of the MVGs. The results reveal the lift-off of the wake away from the wall f...
Investigation of Mars' ionospheric response to solar energetic particle events
Uluşen, Demet; Brain, David A.; Luhmann, Janet G.; Mitchell, David L. (2012-12-11)
We investigate the effects of solar energetic particle (SEP) events on the Martian ionosphere using observations from the Mars Global Surveyor (MGS) Electron Reflectometer (ER) and Radio Science (RS) experiments. Although MGS/ER is not designed to measure solar storm particles, it detects SEPs as increased instrument background. Using this proxy for SEP fluxes near Mars, we compare electron density profiles obtained from the RS experiment during periods of high and low SEP activity. Six case studies show no...
Identification techniques for highly boosted W bosons that decay into hadrons
Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2014-12-01)
In searches for new physics in the energy regime of the LHC, it is becoming increasingly important to distinguish single-jet objects that originate from the merging of the decay products of W bosons produced with high transverse momenta from jets initiated by single partons. Algorithms are defined to identify such W jets for different signals of interest, using techniques that are also applicable to other decays of bosons to hadrons that result in a single jet, such as those from highly boosted Z and Higgs ...
