A model for inflaton induced baryogenesis and its phenomenological consequences
Journal of High Energy PhysicsIn this study, we introduce a novel approach aimed at addressing the longstanding baryon-anti-baryon asymmetry conundrum. Our proposed mechanism suggests that baryon numbers were generated during the inflationary epoch through the dynamics of the ...

Central rapidity net baryon density and baryon number carriers in high-energy collisions
Frontiers in PhysicsThis article focuses on the experimental progress of net baryon density measurements in the central rapidity region, spanning from the AGS and SPS to the RHIC and LHC energy regimes.

Correlation length of the angular mode for an approximate U(1) symmetry during inflation
Physics Letters B, 2023 It is known that a light scalar field obtains fluctuations in the de Sitter inflationary background. Such fluctuations could provide an initial condition for baryogenesis through the Affleck-Dine mechanism, where an approximate U(1)B symmetry is usually ...

Magnetic Hopfions as Local Rotations of the Uniform Magnetization Background
physica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 12, December 2025.The Hopf mapping of 3D coordinate space to the unit sphere m2 = 1 in the magnetization space m(r) can be parametrized by some angles. These angles are used to define a local rotation matrix to restore the hopfion magnetization configuration from the uniformly magnetized state for any Hopf indices.

Meson-baryon threshold effects in the light-quark baryon spectrum [PDF]
, 2014 We argue that selected S wave meson-baryon channels may play a key role in matching poor baryon mass predictions from quark models with data. The identification of these channels with effective inelastic channels in data analysis allows us to derive a ...

Signatures of baryon junctions in semi-inclusive deep inelastic scattering
Physics Letters BLocal gauge invariance of the baryon wave function leads to the emergence of a baryon junction, where three (or N, in SU(N) gauge theory) string operators merge.

Fortschritte der Physik, Volume 73, Issue 9-10, October 2025.Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

The QCD phase diagram at zero and small baryon density [PDF]
, 2012 I review recent developments in determining the QCD phase diagram by means of lattice simulations. Since the invention of methods to side-step the sign problem a few years ago, a number of additional variants have been proposed, and progress has been ...

Baryon-baryon interactions in effective field theory
, 2009 Current activities in the description of baryon-baryon systems are reviewed. In particular, recent results for the hyperon-nucleon and hyperon-hyperon interactions as well as for strangeness S=-3 to -4 baryon-baryon systems, obtained to leading or der ...

Direct baryogenesis in the broken phase
Journal of High Energy Physics, 2020 We show a new mechanism for baryogenesis where the reheating temperature can be smaller than the electroweak scale. The baryon number symmetry is violated by a dimension nine operator which conserves a baryon parity. A high energy quark from the decay of
