The measurement of b-jet production in p-Pb collisions addresses several key points like pQCD production cross-section, cold nuclear matter effect and base line for nucleus-nucleus collisions. The main focus of the talk is to measure the bottom quark jet (b-jet) production in p-Pb collisions at √sNN = 5.02 TeV in the ALICE experiment at the LHC. The measurement of b-jet cross-section agrees well with the NLO pQCD calculations within the experimental and theoretical uncertainties. Apart from the experimental measurements, the talk includes the phenomenological study of heavy quark propagation and chromo-electromagnetic field fluctuations present in the QGP medium. We estimate the effect of the color field fluctuations on the heavy quark transport coefficients (drag and diffusion coefficient), shear viscosity to entropy density ratio (η/s) of the QGP; and nuclear modification factors (RAA) of open charm (D mesons), open beauty mesons (B mesons) and hidden charm (J/Ψ) mesons. We find that these fluctuations result a reduction of the drag and diffusion coefficients of heavy quarks, as these fluctuations cause heavy quarks to gain energy. We also observe that the value of η/s of the QGP medium increases with the inclusion of these fluctuations and make the calculation of η/s closer to the value obtained in lattice QCD (LQCD) and functional renormalization group calculations. The calculated RAA of the heavy-flavor mesons can describe the measured RAA of D-mesons and B-mesons at the CMS and the ALICE experiments within their uncertainties, when the effect of these fluctuations is included along with the energy loss processes.
