Collisional damping widths of isoscalar giant monopole, isovector giant dipole and isoscalar giant quadrupole excitations for Sn-120 and Pb-208 at zero and finite temperatures are calculated within Thomas-Fermi approximation by employing a recently proposed modified Skyrme force and the results are compared with previous works.

Collisional damping of giant monopole and quadrupole resonances Yildirim, S; Gokalp, A; Yılmaz, Osman; Ayik, S (2001-03-01) Collisional damping widths of giant monopole and quadrupole excitations for Sn-120 and Pb-208 at zero and finite temperatures are calculated within Thomas-Fermi approximation by employing the microscopic in-medium cross-sections of Li and Machleidt and the phenomenological Skyrme and Gogny forces, and are compared with each other. The results for the collisional widths of giant monopole and quadrupole vibrations at zero temperature as a function of the mass number show that the collisional damping of giant ...
Collisional damping of giant dipole resonance in Sn-120 and Pb-208 Gokalp, A; Yılmaz, Osman; Yildirim, S; Ayik, S (2001-03-01) We investigate the collisional damping of giant dipole resonance at finite temperature in the basis of a non-Markovian transport approach. We perform our calculations in Thomas-Fermi approximation by employing the microscopic in-medium cross-sections of Li and Machleidt and the phenomenological Gogny force. The results account for about 30% of the observed widths in Sn-120 and Pb-208 at finite temperatures.
Collisional damping of nuclear collective vibrations in a non-Markovian transport approach Ayik, S; Yılmaz, Osman; Gokalp, A; Schuck, P (1998-09-01) A detailed derivation of the collisional widths of collective vibrations is presented in both quantal and semiclassical frameworks by considering the linearized limits of the extended time-dependent Hartree-Fock and the Boltzmann-Uehling-Uhlenbeck model with a non-Markovian binary collision term. Damping widths of giant dipole and giant quadrupole excitations are calculated by employing an effective Skyrme force, and the results are compared with giant dipole resonance measurements in lead and tin nuclei at...
Electroweak production of two jets in association with a Z boson in proton-proton collisions root s =13 TeV Sirunyan, A. M.; et. al. (Springer Science and Business Media LLC, 2018-07-01) A measurement of the electroweak (EW) production of two jets in association with a Z boson in proton-proton collisions at root s = 13 TeV is presented, based on data recorded in 2016 by the CMS experiment at the LHC corresponding to an integrated luminosity of 35.9 fb(-1). The measurement is performed in the lljj final state with l including electrons and muons, and the jets j corresponding to the quarks produced in the hard interaction. The measured cross section in a kinematic region defined by invariant ...
Charged lepton flavor physics and extra dimensions Iltan, E. I. (World Scientific Pub Co Pte Lt, 2007-06-28) We estimate the charged lepton electric dipole moments and the branching ratios of radiative lepton flavor violating decays in the framework of the two Higgs doublet model with the inclusion of two extra dimensions. Here, we consider that the new Higgs doublet is accessible to one of the extra dimensions with a Gaussian profile and the fermions are accessible to the other extra dimension with uniform zero-mode profile. We observe that the numerical values of the physical quantities studied enhance with the ...
