moody thing accounts for most of the matter in the universe , and yet we do it very little about it . Scientists around the world are inching closer and closer to a discovery , and although we are yet to directly observe it , we are shrinking the puddle of possible masse these particles can have .
TheLarge Underground Xenon(LUX ) dingy matter experiment is the most advanced dour matter detector in the world , and now a new set of calibrations has dramatically improve its sensitiveness . LUX is looking for sapless interactive monolithic subatomic particle ( WIMPs ) , speck which have many time the mass of a proton but scarcely interact with other matter .
“ We have improved the sensitiveness of LUX by more than a broker of 20 for humbled - mass non-white matter particles , importantly enhancing our ability to look for WIMPs , ” said Rick Gaitskell , prof of physics at Brown University and cobalt - spokesperson for the LUX experimentation , in astatement .
“ It is vital that we continue to push the capabilities of our detector in the lookup for the problematical dark matter particle . ”
The new research is draw in a paper submitted to Physical Review Letters and available onArXiv . The squad has re - examined the information pile up during the first 95 - day search in 2013 and was capable to rule out low - mass WIMPs antecedently account to be find .
The demodulator consists of a tank filled with 370 kilograms ( 815 pounds ) of Xe surrounded by 61 photomultiplier tubes . On very rarified occasion a WIMP attain a atomic number 54 molecule , and as the atom cringe it emits a newsbreak of igniter which is find by the electron tube .
LUX has not detected a single WIMP yet , but its unmatched sensitivity permit the team to dominate out huge plenty ranges that wimp might have . The detector is the best there is at non - detections of dark matter , as weird as that may sound .
The previous ladder began in 2014 and is expected to continue until June 2016 . This run will be more than four times longer than the previous one . And the team is hoping for an literal detection of dark matter time around .
