Scalar and vector self-energies of heavy baryons in nuclear medium

چکیده
The in-medium sum rules are employed to calculate the shifts in the mass and residue as well as the scalar and vector self-energies of the heavy [Formula: see text] and [Formula: see text] baryons, with Q being b or c quark. The maximum shift in mass due to nuclear matter belongs to the [Formula: see text] baryon and it is found to be [Formula: see text]. In the case of residue, it is obtained that the residue of [Formula: see text] baryon is maximally affected by the nuclear medium with the shift [Formula: see text]. The scalar and vector self-energies are found to be [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text].

Antibaryons in massive heavy ion reactions: Importance of potentials.
In the framework of RQMD we investigate antiproton observables in massive heavy ion collisions at AGS energies and compare to preliminary results of the E878 collaboration. We focus here on the considerable influence of the real part of an antinucleon–nucleus optical potential on the ¯ p momentum spectra. Antibaryon production is a promising observable for collective effects in nucleus–nucleus ...
متن کاملPions and kaons at 1-2 A GeV: Effect of in-medium NN → N∆ cross section
Pion multiplicity in heavy-ion collisions at the beam energies of about 1 A GeV [1, 2] is usually overpredicted by transport calculations with vacuum cross sections. Recently [3] we proposed to take into account the in-medium modifications of the NN → N∆ cross section, namely, the exchange pion collectivity, vertex renormalization by the contact nuclear interactions and Dirac effective masses o...
متن کاملQCD sum rules for ∆ isobar in nuclear matter
The self-energies of ∆ isobar propagating in nuclear matter are calculated using the finite-density QCD sum-rule methods. The calculations show that the Lorentz vector self-energy for the ∆ is significantly smaller than the nucleon vector self-energy. The magnitude of the ∆ scalar self-energy is larger than the corresponding value for the nucleon, which suggests a strong attractive net self-ene...
متن کاملPositive and negative parity hyperons in nuclear medium
The effects of nuclear medium on the residue, mass and self energy of the positive and negative parity Σ, Λ and Ξ hyperons are investigated using the QCD sum rule method. In the calculations, the general interpolating currents of hyperons with an arbitrary mixing parameter are used. We compare the results obtained in medium with those of the vacuum and calculate the shifts in the corresponding ...
متن کاملTwo-loop anomalous dimensions of heavy baryon currents in heavy quark effective theory.
We present results on the two-loop anomalous dimensions of the heavy baryon HQET currents J = (qTCΓτq)Γ′Q with arbitrary Dirac matrices Γ and Γ. From our general result we obtain the two-loop anomalous dimensions for currents with quantum numbers of the ground state heavy baryons ΛQ, ΣQ and Σ∗Q. As a by-product of our calculation and as an additional check we rederive the known two-loop anomalo...
