In this context, light on heavy-ion collisions (e. g. p-Pb) are used to assess Cold Nuclear Matter effects (CNM), while elementary hadronic collisions (e. g. proton-proton) provide tests for QCD (Quantum Chromodynamics) based calculations and baseline for studies with heavy- ions. Heavy quarks, i. e. charm and beauty, are very convenient in the characterization of the QGP. They are produced via initial hard parton-parton scatterings at the early stages of the collision and, therefore, they are a self-generated probe for the system created in the reaction. In this work the angular correlation between electrons from heavy-flavour hadron decays and charged particles was studied in pp (2.76 and 7 TeV) and p-Pb (5.02 TeV) collisions at the CERN Large Hadron Collider, using the ALICE detector. The correlation strengths were evaluated as a function of multiplicity in p-Pb collisions. In pp collisions the relative beauty (and charm) contribution to the total heavy-flavour decay electron yield was estimated using the measured correlation distribution and Monte Carlo templates. 002224311 65017 $$2SzGeCERN$$aParticle Physics - Experiment 002224311 65017 $$2SzGeCERN$$aNuclear Physics - Experiment 002224311 690C_ $$aCERN 002224311 690C_ $$aTHESIS 002224311 693__ $$aCERN LHC$$eALICE 002224311 701__ $$aAlarcon do Passo Suaide, Alexandre$$edir. 002224311 8564_ $$uhttp://www.teses.usp.br/teses/disponiveis/43/43134/tde-18012015-125411/pt-br.php$$yserver 002224311 8564_ $$81249437$$s18375408$$uhttps://cds.cern.ch/record/2224311/files/Thesis-2014-Oliveira Filho.pdf 002224311 8564_ $$81249437$$s37107065$$uhttps://cds.cern.ch/record/2224311/files/Thesis-2014-Oliveira Filho.pdf?subformat=pdfa$$xpdfa 002224311 960__ $$a14 002224311 980__ $$aTHESIS
