Group theory approach to unification of gravity with internal symmetry gauge interactions. I [PDF]
, 1991 The infinite group of deformed diffeomorphisms of the spacetime continuum is put into the basis of the gauge theory of gravity. This gives rise to some new ways for unification of gravity with other gauge interactions.

Digital quantum simulation of lattice gauge theories in three spatial dimensions [PDF]
New Journal of Physics, 2018 In the present work, we propose a scheme for the digital formulation of lattice gauge theories with dynamical fermions in 3 + 1 dimensions. All interactions are obtained as a stroboscopic sequence of two-body interactions with an auxiliary system.

Gap Equations and Electroweak Symmetry Breaking [PDF]
, 2006 Recently a new dynamical symmetry breaking model of electroweak interactions was proposed based on interacting fermions. Two fermions of different SU(2) representations form a symmetry breaking condensate and generate the lepton and quark masses.

Quantum simulations of lattice gauge theories using ultracold atoms in optical lattices [PDF]
Reports on progress in physics. Physical Society, 2015 Can high-energy physics be simulated by low-energy, non-relativistic, many-body systems such as ultracold atoms? Such ultracold atomic systems lack the type of symmetries and dynamical properties of high energy physics models: in particular, they ...

Hide and seek: how PDFs can conceal new physics
Journal of High Energy Physics, 2023 The interpretation of LHC data, and the assessment of possible hints of new physics, require the precise knowledge of the proton structure in terms of parton distribution functions (PDFs). We present a systematic methodology designed to determine whether

Fermionic Field Theory and Gauge Interactions on Random Lattices
, 1993 Random-lattice fermions have been shown to be free of the doubling problem if there are no interactions or interactions of a non-gauge nature. However, gauge interactions impose stringent constraints as expressed by the Ward-Takahashi identities which ...

Gravitino constraints on models of neutrino masses and leptogenesis [PDF]
, 1998 In the supersymmetric extensions of the standard model, neutrino masses and leptogenesis requires existence of new particles. We point out that if these particles with lepton number violating interactions have standard model gauge interactions, then they

Gauge principle revisited: Towards a unification of space–time and internal gauge interactions [PDF]
, 2002 The minimal coupling principle is revisited under the quantum perspectives of the space–time symmetry. This revision is better realized on a group approach to quantization (GAQ) where group cohomology and extensions of groups play a preponderant role. We

CP violation and mixing in technicolor models [PDF]
, 2004 Vacuum alignment in technicolor models provides an attractive origin for the quarks' CP violation and, possibly, a natural solution for the strong-CP problem of QCD. We discuss these topics in this paper.

Probing new spin-independent interactions through precision spectroscopy in atoms with few electrons [PDF]
, 2017 The very high precision of current measurements and theory predictions of spectral lines in few-electron atoms allows to efficiently probe the existence of exotic forces between electrons, neutrons and protons.
