We report a first search for weakly interacting massive particles (WIMPs) using the background rejection capabilities of SuperCDMS. An exposure 577 kg days was analyzed WIMPs with mass <30 GeV/c(2), signal region blinded. Eleven events were observed after unblinding. set an upper limit on spin-independent WIMP-nucleon cross section 1.2×10(-42) cm(2) at 8 GeV/c(2). This result is in tension WIMP interpretations recent experiments and probes new parameter space scattering masses <6
We report results of a search for weakly interacting massive particles (WIMPS) with the silicon detectors CDMS II experiment. This blind analysis 140.2 kg day data taken between July 2007 and September 2008 revealed three WIMP-candidate events surface-event background estimate 0.41(-0.08)(+0.20)(stat)(-0.24)(+0.28)(syst). Other known backgrounds from neutrons 206Pb are limited to <0.13 <0.08 at 90% confidence level, respectively. The exposure this is equivalent 23.4 recoil energy range 7-100...
The CDMS low ionization threshold experiment (CDMSlite) uses cryogenic germanium detectors operated at a relatively high bias voltage to amplify the phonon signal in search for weakly interacting massive particles (WIMPs). Results are presented from second CDMSlite run with an exposure of 70 kg day, which reached energy electron recoils as 56 eV. A fiducialization cut reduces backgrounds below those previously reported by CDMSlite. New parameter space WIMP-nucleon spin-independent cross...
SuperCDMS is an experiment designed to directly detect Weakly Interacting Massive Particles (WIMPs), a favored candidate for dark matter ubiquitous in the Universe. In this paper, we present WIMP-search results using calorimetric technique call CDMSlite, which relies on voltage- assisted Luke-Neganov amplification of ionization energy deposited by particle interactions. The data were collected with single 0.6 kg germanium detector running 10 live days at Soudan Underground Laboratory. A low...
CDMS II data from the five-tower runs at Soudan Underground Laboratory were reprocessed with an improved charge-pulse fitting algorithm. Two new analysis techniques to reject surface-event backgrounds applied 612 kg days germanium-detector weakly interacting massive particle (WIMP)-search exposure. An extended was also completed by decreasing 10 keV threshold $\ensuremath{\sim}5\text{ }\text{ }\mathrm{keV}$, increase sensitivity near a WIMP mass of $8\text{ }\mathrm{GeV}/{c}^{2}$. After...
We examine the consequences of effective field theory (EFT) dark matter--nucleon scattering for current and proposed direct detection experiments. Exclusion limits on EFT coupling constants computed using optimum interval method are presented SuperCDMS Soudan, CDMS II, LUX, necessity combining results from multiple experiments in order to determine matter parameters is discussed. demonstrate that spectral differences between standard model a general interaction can produce bias when...
We report results of a search for Weakly Interacting Massive Particles (WIMPs) with the Si detectors CDMS II experiment. This describes blind analysis first data taken II's full complement in 2006-2007; from this exposure using Ge have already been presented. observed no candidate WIMP-scattering events an 55.9 kg-days before cuts, expected background ~1.1 events.

The SuperCDMS experiment in the Soudan Underground Laboratory searches for dark matter with a 9-kg array of cryogenic germanium detectors. Symmetric sensors on opposite sides measure both charge and phonons from each particle interaction, providing excellent discrimination between electron nuclear recoils, surface interior events. Surface event rejection capabilities were tested two 210Pb sources producing ∼130 beta decays/hr. In ∼800 live hours, no events leaked into 8–115 keV signal...
While the standard model of particle physics does not include free particles with fractional charge, experimental searches have ruled out their existence. We report results from Cryogenic Dark Matter Search (CDMS II) experiment that give first direct-detection limits for cosmogenically produced relativistic electric charge lower than e/6. A search tracks in six stacked detectors each two CDMS II towers finds no candidates, thereby excluding new parameter space charges between e/6 and e/200.
In the study carried out in line with stated purposes, monthly rain, humidity and temperature data, wheat production amount, productivity data of Konya province between 1980-2020 were used. Using these estimation was performed (Gated Recurrent Units) GRU Long Short Term Memory (LSTM) methods, which are Neural Network (RNN) based algorithms. When performance examined implemented GRU-based model, 0.9550, 0.0059, 0.0280, 0.0623, 7.45 values obtained for R2 score, MSE, RMSE, MAE MAPE values,...
Matter, as we know it, makes up less than 5% of the Universe.Various astrophysical observations have confirmed that one quarter Universe and most matter content in is made Dark Matter.The nature Matter yet to be discovered biggest questions Physics.Particle Physics combined with measurements abundance gives rise a candidate called Weakly Interacting Massive Particle (WIMP).The low density WIMPs galaxies extremely weak interaction ordinary make detection WIMP an extraordinarily challenging...
