Parametrized leptogenesis from linear seesaw

European Physical Journal C: Particles and Fields, 2020
We present a purely linear seesaw mechanism in a mirror left-right symmetric framework and then realize a novel leptogenesis scenario for parametrizing the cosmic baryon asymmetry by the charged lepton masses, the light Majorana neutrino mass matrix and ...

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 ...

Drag force and heavy quark potential in a rotating background

Journal of High Energy Physics
We explored the gravity dual of a rotating quark-gluon plasma by transforming the boundary coordinates of the large black hole limit of Schwarchild-AdS5 metric.

Soft Flexible Skin Conformable Nanocomposites as a Platform for Electroceutical and Orthopedic Applications

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

Lepton asymmetry and the cosmic QCD transition

, 2009
We study the influence of lepton asymmetry on the evolution of the early Universe. The lepton asymmetry $l$ is poorly constrained by observations and might be orders of magnitude larger than the baryon asymmetry $b$, $|l|/b \leq 2\times 10^8$.

Probing transverse momentum broadening via dihadron and hadron-jet angular correlations in relativistic heavy-ion collisions

Physics Letters B, 2017
Dijet, dihadron, hadron-jet angular correlations have been reckoned as important probes of the transverse momentum broadening effects in relativistic nuclear collisions.

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.

Polarization observables in lepton-deuteron elastic scattering including the lepton mass

, 2014
Expressions for the unpolarized differential cross section and for various polarization observables in the lepton-deuteron elastic scattering, $\ell+D\to \ell+D$, $\ell=e$, $\mu$, $\tau$, have been obtained in one-photon-exchange approximation, taking ...

Lepton asymmetry in the primordial gravitational wave spectrum [PDF]

, 2006
Effects of neutrino free streaming is evaluated on the primordial spectrum of gravitational radiation taking both neutrino chemical potential and masses into account. The former or the lepton asymmetry induces two competitive effects, namely, to increase

Assessment of Microbolometer Infrared Cameras for Thermoelastic Stress Analysis

Strain, Volume 61, Issue 1, February 2025.
ABSTRACT A means of simulating the performance of infrared (IR) cameras is described, with the purpose of assessing the suitability of the IR camera for thermoelastic stress analysis (TSA). The approach is demonstrated on two IR cameras containing different sensors: a standard microbolometer and a very low cost microbolometer based thermal core.
