Precision measurement of the W boson decay branching fractions in proton-proton collisions at $\sqrt{s}$ = 13 TeV / CMS Collaboration
The leptonic and inclusive hadronic decay branching fractions of the W boson are measured using proton-proton collision data collected at $\sqrt{s}$ = 13 TeV by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. [...]

Fluidity of the system produced in relativistic pp and heavy-ion collisions: Hadron resonance gas model approach / Scaria, Ronald (Indian Inst. Tech., Kanpur) ; Sahu, Dushmanta (Indian Inst. Tech., Kanpur) ; Singh, Captain R. (Indian Inst. Tech., Kanpur) ; Sahoo, Raghunath (Indian Inst. Tech., Kanpur ; CERN) ; Alam, Jan-e (Calcutta, VECC)
We have estimated the dimensionless parameters such as Reynolds number ($Re$), Knudsen number ($Kn$) and Mach number ($Ma$) for a multi-hadron system by using the excluded volume hadron resonance gas (EVHRG) model along with Hagedorn mass spectrum to include higher resonances in the system. [...]
