The modification of Qˆ is indeed seen in changes of thermal pair combination from |ξ†kξ∼†k| in (4.6) to |ξ∼†k+p2−q|ξ∼†k| and |ξ∼†k+p2−q−q1−q2|ξ∼†k| in (4.7). This happens through the elementary process that incident particles ...
By employing the Omnès representation we can provide a very clean estimate for a certain combination of the curvature and the square radius, whose quark mass dependence could be determined from lattice computations. This study provides an independent access to the quark mass dependence of the ρπ...
From SU(3)-flavor symmetry, the Pcs pentaquark contains a triplet charmed antimeson and antitriplet charmed baryon and is a combination of a singlet and an octet, i.e. 3⊗3¯=1⊕8. The concrete flavor structure of the potential is unessential though, as we are only considering the ...
Since theTmatricesT_acontain effects from two-body interactions in the same combination of (anti-)quark legs only, they are prone to develop singularities in the respective channels, with the quantum numbers of mesons and (anti-)diquarks. The two-body approximation of the four-body equation t...
Here we report on the observation of elliptic and triangular flow patterns of charged particles produced in proton–gold (p+Au), deuteron–gold (d+Au) and helium–gold (3He+Au) collisions at a nucleon–nucleon centre-of-mass energy sNN = 200 GeV. The unique combination of three ...

The final result for the transition magnetic moment, a combination of the quark core and pion cloud effects, turns out to give a value very close to the data. The pion cloud contribution, although small, pulls the final result towards the experimental value. The final result, ${\\\ensurema...
We report here on recent progress in the determination of S-wave and P-wave heavy-quarkonium states at finite temperature. Our results are based on the combination of effective field theories with numerical lattice QCD simulations. These non-perturbative tools allow us to compute the heavy-quark...
Several lattice calculations of a combination of the low energy constants of\nthe chiral Lagrangian, 2\\alpha_8-\\alpha_5, are presented. This combination is\ncritical for the preclusion of a massless up quark. The result found is\n2\\al... DR Nelson,GT Fleming,GW Kilcup 被引量: 0发...
In the tt¯ case, in order to tag the event as such, one usually only requires a single b-jet (out of the two produced) to be identified, and thus the associated efficiency is larger: εtt¯≈1−(1−0.5)2=0.75. The combination of acceptance, analysis requirements, and ...
