john steinbeck: friend of the american common man
in his last years of life americans had almost forgotton steinbeck, and those who had not, occasionally criticized him for supporting and praising the u. s. military intervention in the vietnam war. althought ateinbeck incorporates different themes into his works, each one bears many signs of his concern and sympathy for america and the american common people in particular. steinbecks to a god ...
15 صفحه اولCharm and hidden charm scalar mesons in the nuclear medium
We study the renormalization of the properties of the low lying charm and hidden charm scalar mesons in a nuclear medium, concretely of the D s0 (2317), D 0 (2400) and the theoretical hidden charm state X(3700). We find that for the D s0 (2317), with negligible width at zero density, the width becomes about 100 MeV at normal nuclear matter density, while in the case of the X(3700) the width bec...
متن کاملThe Charm Physics Potential of a Tax&charm Factory*
The charm physics program accessible to a Tau-Charm Factory is summarized. Semileptonic,’ leptonic, hadronic, rare and forbidden charm decay modes are discussed, as well as 00 charm sector. The theoretical b” mixing and CP violation in the 73 ectations in the Standard Model and beyond as well as the experiment capabilities of a Tau-Charm Factory are examined for each of the above processes.
متن کاملInclusive Charm Production at HERA and the Charm
We calculate the contribution to inclusive high tranverse momentum (p T) charm production at HERA from the excitation of charm in the photon. At large values of p T the results of such a calculation, in the structure function language, will be more reliable as it sums the large logs, log(p 2 T =m 2 c), as opposed to calculating the contribution of the 2 ! 3 subprocess in xed order of perturbati...
متن کاملThe Charm Quark's Mass
where γ0 = 4. The lattice mass M and, by implication, C0 = C0(M) are specified below. Eq. (1) omits higher orders in the gauge coupling α and power-law artifacts. This paper determines the charm quark’s mass, m̄ch, from quenched calculations of the c̄c spectrum. To anticipate the main sources of uncertainty, let us recall recent determinations the average of the up and down quarks’ masses [1,2]. ...
