9~11行目

Fig.4: mt -spectra

Among two distinctive features of mt spectrum

in relativistic heavy ion collisions,

only the former one is owing to the expansion of fireball.

45頁

6~9行目

For lower momentum, mainly because of multiple scattering,

for higher momentum, mainly due to position resolution.

mt y pt
(3) mt分布の誤差に関してアクセプタンスのy, pt相関の影響の考察

77頁

14~17行目

While geometrical acceptance has y-pt (or mt) correlation,

the effect is smaller (~2.5%) in the pion mt-spectrum.

● Dominated by combinatorial background

● Effect of two-track separation are evaluated to be small

( Chamber resolution (~some mm)

< Nominal track distance (~few tens cm) )
