with no net local colour charges or currents. As a heavy quark moves through the QGP, it disturbs the medium, generating local charges and currents. These disturbances create colour fields, which interact with the particles in the medium, inducing...
C Pallis,ME Gomez - 《Sissa》 被引量: 144发表: 2003年 Dirac Fermions in Borophene Honeycomb structures of group IV elements can host massless Dirac fermions with nontrivial Berry phases. Their potential for electronic applications has attracted great interest and spurred a broad search for new Di...
The data for the mesonic correlation functions can be fitted to the previous functions, obtaining Mi. The time interval which should be used in the fit can be chosen by checking that the effective mass meff (t) = log(G(t)/G(t + 1)) reaches a plateau value in the time interval ...

pole- and PS-scheme. In figure 1 we have plotted the PS-mass as a function of n and the influence of the scale variations. The largest contribution to the error comes from the soft scale. Adding the errors from all input parameters quadrati- cally, our final results for the ma...
For instance, at lowest order the relation between the mass of a pseudoscalar meson composed of quarks with masses m1 and m2 is m2PS = B0(m1 + m2) + . . . , (5.80) where the ellipses represent higher orders in the chiral expansion. Similar expres- sions are derived for vector ...
1, but for LO + parton-shower (PS) generation. The uncertainty bands are calculated by reweighting the ME and up to nPS shower emissions. In the upper four plots, nPS = 3. In the lower plots, nPS is varied for comparison. The scale uncertainties do not change with nPS and are ...
