The procedure for the energy calibration of the high granularity electromagnetic calorimeter PHOS of the ALICE experiment is presented. The methods used to perform the relative gain calibration, to evaluate the geometrical alignment and the corresponding correction of the absolute energy scale, to obtain the nonlinearity correction coefficients and finally, to calculate the time-dependent calibration corrections, are discussed and illustrated by the PHOS performance in proton-proton (pp) collisions at $\sqrt{s}=13$ TeV.

Measurement of D$^0$, D$^+$, D$^*$ and D$_s$ production in pp collisions at $\sqrt{s}$ = 5.02 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adhya, Souvik Priyam (Calcutta, VECC) ; Adler, Alexander (Goethe U., Frankfurt, Inst.

The measurements of the production of prompt D$^0$, D$^+$, D$^*$ and D$_s$ mesons in proton-proton (pp) collisions at $\sqrt{s}$ = 5.02 TeV with the ALICE detector at the Large Hadron Collider (LHC) are reported. D mesons were reconstructed at mid-rapidity ($|y|<0.5$) via their hadronic decay channels ${\rm D}^0 \to {\rm K}^-\pi^+$, ${\rm D}^+\to {\rm K}^-\pi^+\pi^+$, ${\rm D}^{*+} \to {\rm D}^0 \pi^+ \to {\rm K}^- \pi^+ \pi^+$, ${\rm D^{+}_{s}\to \phi\pi^+\to K^{+} K^{-} \pi^{+}}$, and their charge conjugates.

Event-shape and multiplicity dependence of freeze-out radii in pp collisions at $\sqrt{s}$ = 7 TeV / Acharya, Shreyasi (Calcutta, VECC) ; Torales - Acosta, Fernando (UC, Berkeley) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Adhya, Souvik Priyam (Calcutta, VECC) ; Adler, Alexander (Goethe U., Frankfurt, Inst.

Tech., Mumbai) et al.
Two-particle correlations in high-energy collision experiments enable the extraction of particle source radii by using the Bose-Einstein enhancement of pion production at low relative momentum $q\propto 1/R$. It was previously observed that in pp collisions at $\sqrt{s}$ = 7 TeV the average pair transverse momentum $k_{\rm{T}}$ range of such analyses is limited due to large background correlations which were attributed to mini-jet phenomena.
