Single Transverse-Spin Asymmetry in Very Forward and Very Backward Neutral Particle Production for Polarized Proton Collisions at sqrt{s} = 200 GeV (2006)

Fukao, Y., Togawa, M., Bazilevsky, A., Bland, L. C., Bogdanov, A., Bunce, G., ...

In the 2001-2002 running period of the Relativistic Heavy Ion Collider (RHIC), transversely polarized protons were accelerated to 100 GeV for the first time, with collisions at sqrt{s} = 200 GeV. We...

Nuclear-matter modification of decay widths in the $\phi \to e^{+}e^{-}$ and $\phi \to K^{+}K^{-}$ channels (2006)

Sakuma, F., Chiba, J., En'yo, H., Fukao, Y., Funahashi, H., Hamagaki, H., ...

The invariant mass spectra of $\phi \to K^{+}K^{-}$ are measured in 12 GeV $p+A$ reactions in order to search for the in-medium modification of $\phi$ mesons. The observed $K^{+}K^{-}$ spectra are...

Nuclear mass number dependence of inclusive production of omega and phi mesons in 12 GeV p + A collisions (2006)

Tabaru, T., En'yo, H., Muto, R., Naruki, M., Yokkaichi, S., Chiba, J., ...

The inclusive production of omega and phi mesons is studied in the backward region of the interaction of 12 GeV protons with polyethylene, carbon, and copper targets. The mesons are measured in e^+...

Evidence for in-medium modification of the $\phi$ meson at normal nuclear density (2005)

Muto, R., En'yo, H., Naruki, M., Tabaru, T., Yokkaichi, S., Chiba, J., ...

Invariant mass spectra of e+e- pairs have been measured in 12 GeV p+A reactions to detect possible in-medium modification of vector mesons. Copper and carbon targets are used to study the...

Experimental Signature of Medium Modifications for rho and omega Mesons in the 12 GeV p + A Reactions (2005)

Naruki, M., Funahashi, H., Fukao, Y., Kitaguchi, M., Ishino, M., Kanda, H., ...

The invariant mass spectra of e+e- pairs produced in 12-GeV proton-induced nuclear reactions are measured at the KEK Proton-Synchrotron. On the low-mass side of the omega meson peak, a significant...

Observation of $\rho/\omega$ meson modification in nuclear matter (2001)

Ozawa, K, Enyo, H, Funahashi, H, Kitaguchi, M, Ishino, M, Kanda, H, ...

Observation of $\rho / \omega$ Meson Modification in Nuclear Matter (2000)

Ozawa, K., En'yo, H., Funahashi, H., Kitaguchi, M., Ishino, M., Kanda, H., ...

We have measured invariant mass spectra of electron-positron pairs in the target rapidity region of 12GeV p+A reactions. We have observed a significant difference in the mass spectra below the...
