Query: Examining the event-shape dependent modifications to charged-particle
  transverse momentum spectra and elliptic flow in p-Pb collisions at energies
  available at the CERN Large Hadron Collider   Purported signatures of collective dynamics in small systems like
proton-proton (pp) or proton-nucleus (p-A) collisions still lack unambiguous
understanding. Despite the qualitative and/or quantitative agreement of the
data to hydrodynamic models, it has remained unclear whether the harmonic flows
in small systems relate to the common physical picture of hydrodynamic
collectivity driven by the initial geometry. In the present work, we aim to
address this issue by invoking a novel concept of Event Shape Engineering
(ESE), which has been leveraged to get some control of the initial geometry in
high-energy heavy-ion collisions. We utilise ESE by constructing a reference
flow vector, $q_{2}$ that allows to characterise an event based on it's
ellipticity. Applying this technique on a data set, simulated from a 3+1D
viscous hydrodynamic model EPOS3, we study the event-shape dependent
modifications to some of the bulk properties like, inclusive transverse
momentum ($p_{T}$) spectra and $p_{T}$-differential $v_{2}$ for p-Pb collisions
at 5.02 TeV. Selecting events on the basis of different magnitudes of reference
flow vector $q_{2}$, we observe a hint of event-shape induced modifications of
$v_{2}$ as a function of $p_{T}$ but, the inclusive $p_{T}$-spectra of charged
particles seem to be insensitive to this event-shape selection.
