  Abstract:
spatial → the spatial
femtscopic → femtoscopic
We present dependence of the invariant radii on pair transverse momentum at  
the different charged particle multiplicity per event.

→ We present the invariant radii's dependence on pair transverse momentum  
at the differently charged particle multiplicity per event.

Introduction:
The quantum statistics → quantum statistics
Femtoscopy can be used to extract the space-time characteristics of the  
particle emitting source which is created in the p+p, p+A or A+A collisions  
[1–4]. → Femtoscopy can extract the particle emitting source's space-time 
 
characteristics created in the p+p, p+A, or A+A collisions [1–4].
The femtoscopic radii, extracted from these correlations, describe the  
emission source at the moment of kinetic freeze-out which is the last stage  
of particle interactions. → The femtoscopic radii, extracted from these  
correlations, describe the emission source at the moment of kinetic  
freeze-out, which is the last particle interaction stage.

different charged particle → differently charged particle
than has all experimental → with all experimental

Analysis details
In the collider, during the readout of the event in the gas volume of the  
TPC, several collisions may occur which may lead to the pile-up. → In the  
collider, during the readout of the event in the TPC's gas volume, several  
collisions may occur, which may lead to the pile-up.
The upper value of the momentum cut was chosen based on the maximum possible  
value allowing the reasonable separation of pions and kaons in TPC. → The

allowing the reasonable separation of pions and kaons in TPC

Track merging occurs when two tracks close to each other in the TPC and  
reconstructed as one due to the fusion of the ionization cluster. → Track  
merging occurs when two tracks close to each other in the TPC and

Influence on correlation function → influence correlation function
Presented on the Fig → presented in the Fig (also other places on the  
figure → in the figure)
with assumption → , assuming
The another → another
Lorenzian shape and→ Lorenzian shape, and
where correlation function → where the correlation function
to test → for testing
has Gaussian shape → has a Gaussian shape
It is seen that the correlation functions are reasonably described by the  
fits → It is seen that the fits reasonably describe the correlation  
functions.
It is seen that the fits reasonably describe the correlation functions. →  
The radii increase with increasing multiplicity, as one would expect from the 
 
collisions' simple geometric picture.

Figure 1: replace this plot with this including Lorenzian’s fits too.
