TRIPLICITY OF QUARKS AND LEPTONS [PDF]
Modern Physics Letters A, 2005 Quarks come in three colors and have electric charges in multiples of one-third. There are also three families of quarks and leptons. Though the first two properties can be understood in terms of unification symmetries such as SU(5), SO(10), or E6, why should there only be three families remains a mystery. We propose how all three properties involving

An Algebraic Roadmap of Particle Theories
Annalen der Physik, Volume 537, Issue 4, April 2025.The SO(10) grand unified theory, the Georgi–Glashow SU(5) grand unified theory, the Pati–Salam model, the Left–Right Symmetric model, and the Standard model have been studied extensively since the 1970s. Recasting these models in a division algebraic language elucidates how they are each in fact connected.

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

Dijet asymmetry in the resummation improved perturbative QCD approach
Physics Letters B, 2018 We develop the first systematic theoretical approach to dijet asymmetries in hadron–hadron collisions based on the perturbative QCD (pQCD) expansion and the Sudakov resummation formalism.

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 113, Issue 3, March 2025.ABSTRACT Designing biomimetic substrates and electrodes for bioelectronic devices with the necessary mechanical, electrical, and biological properties is critical considering the potential mismatch between soft tissue and rigid electronics, where incompatibility leads to decreased device performance, delamination, inflammation, and discomfort. There is

Visible GeV ALP from TeV Vector‐Like Leptons
Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Rare W → B c + γ decay up to the NNLO and NLL accuracy in QCD
Journal of High Energy PhysicsWe perform a detailed theoretical study of the rare radiative decay of the W boson into a B c meson and an on-shell photon. The decay amplitude is described by two independent form factors, which are calculated up to the next-to-next-to-leading order ...

Relating lepton mixing angles with lepton mass hierarchy [PDF]
International Journal of Modern Physics A, 2016 We revisit the possibility of relating lepton mixing angles with lepton mass hierarchies in a model-independent way. Guided by the existence of such relations in the quark sector, we first consider all the mixing angles, both in charged lepton and neutrino sectors to be related to the respective mass ratios.

Multi-Lepton and Isolated Lepton Events at HERA
, 2009 Measurements of the production of events containing isolated high energy leptons (electrons and muons) produced in ep collisions have been performed with the H1 and ZEUS detectors at HERA, using data collected in the period 1994-2007. Topologies with more than one charged lepton or with a charged lepton in coincidence with missing transverse momentum ...
