Query: Response relation in Pb-Pb and p-Pb collisions at 5.02 TeV   We carry out simulations using a multi-phase transport (AMPT) model to
describe the response relation between $v_2$ and $\varepsilon_2$ in Pb-Pb and
p-Pb collisions at $\sqrt{s_{NN}}=5.02$ TeV, respectively. To simulate such
relation, two methods have been introduced in the calculation: one is the
directed response (DR) method, which correlates the outgoing particles with the
initial anisotropy directly, and the other one is the cumulants response (CR)
method, which is constructed from a cumulants correlation between outgoing
particles. Based on calculations of the DR and CR methods, the response
relations as a function of the transverse momentum are both shown in Pb-Pb and
p-Pb collisions. By comparing the DR and CR methods, we found that the linear
response relations are almost identical in all the present collisions. Similar
results of linear+cubic response relations are also shown in the higher
multiplicity systems, and it has become a significant difference in the lower
multiplicity systems, i.e., the peripheral Pb-Pb collisions and p-Pb
collisions. Throughout the whole $p_{T}$-dependent simulations, the $\kappa_2$
in the linear response and in the linear+cubic response are almost identical,
except for in the lower multiplicity systems by the DR method. If one
implements a pseudorapidity gap by the CR calculation, the $p_{T}$-dependent
and $\eta$-independent response relations are similarly shown in peripheral
Pb-Pb systems and p-Pb systems, which may imply that a collective response
exists in the most central p-Pb collisions. These collective behaviors are
dominantly produced on the stage of the medium expansions.
