The mass spectrum of compact remnants from the parsec stellar evolution tracks [PDF]

open access: yes, 2015
The mass spectrum of stellar-mass black holes (BHs) is highly uncertain. Dynamical mass measurements are available only for few ( 10) BHs in X-ray binaries, while theoretical models strongly depend on the hydrodynamics of supernova (SN) explosions and on

USE OF GAMMA–GAMMA COINCIDENCE TECHNIQUE IN INVESTIGATING GAMMA – RAYS ATTENUATION AT DIFFERENT ENERGIES

open access: yesTikrit Journal of Pure Science, 2023
A gamma–gamma fast –slow coincidence spectrometer composed of two 3"×3"NaI(Tl) detectors  and peripheral electronics is used in investigating some effects on the photo peak  after the penetration of gamma –rays from lead.

Matching the Hagedorn mass spectrum with lattice QCD results [PDF]

open access: yes, 2015
Based on recent Lattice QCD (LQCD) results obtained at finite temperature, we discuss modeling of the hadronic phase of QCD in the framework of Hadron Resonance Gas (HRG) with discrete and continuous mass spectra.

Renormalized spectrum of quasiparticle in limited number of states, strongly interacting with two-mode polarization phonons at T=0 K

open access: yesCondensed Matter Physics, 2021
Within unitary transformed Hamiltonian of Fröhlich type, using the Green's functions method, exact renormalized energy spectrum of quasiparticle strongly interacting with two-mode polarization phonons is obtained at T=0 K in a model of the system with ...

Measuring hadron properties at finite temperature [PDF]

open access: yes, 1995
We estimate the numbers and mass spectra of observed lepton and kaon pairs produced from $\phi$ meson decays in the central rapidity region of an Au+Au collision at lab energy 11.6 GeV/nucleon.

Synthesis and investigation of mass spectra of some novel benzimidazole derivatives

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2008
2-Substituted benzimidazoles (3) and (4a-c) were prepared via condensation of ethyl 2-thionyl-pyruvate (1) and hydrazidoyl derivatives (2a-c) with o-phenylene diamine in acetic acid.

ppbar enhancement in B and J/Psi decay

open access: yes, 2006
The near-threshold enhancement in the ppbar invariant mass spectrum from the B^+ -> K^+ ppbar decay reported recently by the BaBar Collaboration is studied within the J\"ulich NNbar model.

T-duality in M-theory and supermembranes [PDF]

open access: yes, 1997
The (q_1,q_2) SL(2,Z) string bound states of type IIB superstring theory admit two inequivalent (T-dual) representations in eleven dimensions in terms of a fundamental 2-brane.

Conditions for statistical determination of the neutrino mass spectrum in radiative emission of neutrino pairs in atoms [PDF]

open access: yes, 2015
The photon spectrum in macrocoherent atomic de-excitation via radiative emission of neutrino pairs (RENP) has been proposed as a sensitive probe of the neutrino mass spectrum, capable of competing with conventional neutrino experiments.
