  To describe the transverse distribution of charged hadrons at 1.96 TeV
observed by the CDF collaboration, we propose a formula with two component,
namely, hadron gas distributions and inverse power laws. The data collected at
0.9, 2.76, 7, and 13 TeV by the ALICE, CMS, and ATLAS collaborations are also
analyzed using various models including single component models as well as two
component models. The results by using modified version of Hagedorn's formula
are compared with those by using the two component model proposed by Bylinkin,
Rostovtsev and Ryskin (BRR). Moreover, we show that there is an interesting
interrelation among our the modified version of Hagedorn's formula, a formula
proposed by ATLAS collaboration, and the BRR formula.
