Tensor Condensate Accompanied by Chiral Transition in a Strong Magnetic Field

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
We investigate tensor condensates and chiral condensates in the (2 + 1)‐flavor Nambu–Jona–Lasinio model at finite temperature and density in the presence of a strong magnetic field. The emergence of the tensor condensate is attributed to the four‐fermion interaction.

Gluonic vacuum, q-theory, and the cosmological constant

, 2009
In previous work, q-theory was introduced to describe the gravitating macroscopic behavior of a conserved microscopic variable q. In this article, the gluon condensate of quantum chromodynamics is considered in terms of q-theory.

Heavy Quarkonium States With Baryonic Chemical Potential

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
In this work, we have studied the dissociation behavior of 1S and 2S states of quarkonium using quasiparticle approach where the Debye mass depends on baryonic chemical potential. The binding energies of the quarkonium states has been obtained by using quasiparticle Debye mass which further depends on temperature and baryonic chemical potential (μb ...

Bayesian time‐lapse full waveform inversion using Hamiltonian Monte Carlo

Geophysical Prospecting, Volume 72, Issue 9, Page 3381-3398, November 2024.
Abstract Time‐lapse images carry out important information about dynamic changes in Earth's interior, which can be inferred using different full waveform inversion schemes. The estimation process is performed by manipulating more than one seismic dataset, associated with the baseline and monitors surveys.

Running of the top quark mass at NNLO in QCD

Journal of High Energy Physics
The running of the top quark mass (m t) is probed at the next-to-next-to-leading order in quantum chromodynamics for the first time. The result is obtained by comparing calculations in the modified minimal subtraction ( $$\overline{{\text{MS ...

Antimatter Gravity and the Results of the ALPHA‐g Experiment

Annalen der Physik, Volume 536, Issue 7, July 2024.
The recent results of the ALPHA‐g experiment, which show gravitational attraction between antihydrogen atoms and the Earth, seem to undermine the success of repulsive‐gravity models in the cosmological field. Analyzing the theory of CPT gravity, two solutions are found that are consistent with the experimental results, while preserving the large‐scale ...

Bubble dynamics in a QCD-like phase diagram

Journal of High Energy Physics
A line of first-order phase transitions is conjectured in the phase diagram of Quantum Chromodynamics at non-zero baryon density. If this is the case, numerical simulations of neutron star mergers suggest that various regions of the stars may cross this ...
