1 Beauty decay electrons in p-pb collisions using displaced electrons in ALICE Soyeon Cho Inha University (Advised by Jin-Hee Yoon & MinJung Kweon) Heavy Ion Meeting in Andong 1
2 Motivation Study cold nuclear effect Study p+a as a benchmark for A+A Benchmark hard processes to disentangle initial from final state effects Characterize nuclear PDF at small x The gluon density rise rapidly The high energy limit of the gluon is the high gluon density limit The density must saturated for the fixed energy of gluons at high energy Heavy Ion Meeting in Andong 2

4 Analysis method Minimum impact parameter cut Subtract remaining background electrons The impact parameter is the core for this analysis cτ B~500 μm m B ~ 5 GeV/c 2 It is important to ensure the quality of the impact parameter, especially the run by run stability for p-pb Heavy Ion Meeting in Andong 4
