Constraints on neutrino and dark radiation interactions using cosmological observations
, 2012 Observations of the cosmic microwave background (CMB) and large-scale structure (LSS) provide a unique opportunity to explore the fundamental properties of the constituents that compose the cosmic dark radiation background (CDRB), of which the three ...

Studies of Parity Violation in Atoms
Annalen der Physik, Volume 537, Issue 2, February 2025.This article provides an overview of atomic parity violation (APV), emphasizing its role in testing the Standard Model and probing new physics. The review discusses manifestations of APV, including nuclear‐spin‐independent and dependent effects, and explores isotopic comparison as a method for precision measurements.

Neutrino Anisotropies after Planck
, 2013 We present new constraints on the rest-frame sound speed, c_{eff}^2, and the viscosity parameter, c_{vis}^2, of the Cosmic Neutrino Background from the recent measurements of the Cosmic Microwave Background anisotropies provided by the Planck satellite ...

Flavor ratios of extragalactical neutrinos and neutrino shortcuts in extra dimensions
, 2015 The recent measurement of high energy extragalactic neutrinos by the IceCube Collaboration has opened a new window to probe non-standard neutrino properties. Among other effects, sterile neutrino altered dispersion relations (ADRs) due to shortcuts in an

Advanced Functional Materials, Volume 35, Issue 2, January 9, 2025.Many modern detector systems require structured scintillators in combination with photo‐detectors. This requirement can be fulfilled by 3D printing plastic scintillators which becomes more and more relevant. However, the resolution and surface quality of 1‐photon‐based 3D printing techniques are not sufficient for many applications.

Perturbation Theory of Neutrino Oscillation with Nonstandard Neutrino Interactions
, 2009 We discuss various physics aspects of neutrino oscillation with non-standard interactions (NSI). We formulate a perturbative framework by taking \Delta m^2_{21} / \Delta m^2_{31}, s_{13}, and the NSI elements \epsilon_{\alpha \beta} (\alpha, \beta = e ...

A Brief, Biased View of Neutron Star Cooling
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT This is a concise and non‐technical review of topics related to neutron star (NS) cooling, for both young NSs and NSs in low‐mass x‐ray binaries. Neutrino emission from the NS core drives cooling rates, via different processes including Urca processes and pair breaking and formation at the neutron superfluid critical temperature.

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.We obtain the off‐shell nilpotent Becchi–Rouet–Stora–Tyutin (BRST) and anti‐BRST symmetry transformations (corresponding to the infinitesimal classical gauge symmetry transformations) for the modified massive three (2 + 1)‐dimensional (3D) Abelian two‐form gauge theory with a single pseudoscalar field. The latter field (having the negative kinetic term
