Energetic Compact Strokes as the Major Source of Downward Terrestrial Gamma‐Ray Flashes in Winter Thunderstorms

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract Terrestrial gamma‐ray flashes (TGFs) are short bursts of intense gamma radiation associated with lightning discharges. Although thousands of TGFs have been observed from space, TGFs detected at ground level, known as downward TGFs, are still very limited, and their relationship with lightning discharge processes remains elusive. Here we report

Solar neutrinos: beyond standard solar models [PDF]

, 1996
After a short survey of the physics of solar neutrinos, giving an overview of hydrogen burning reactions, predictions of standard solar models and results of solar neutrino experiments, we discuss the solar-model-independent indications in favour of non ...

Probing New Physics with Astrophysical Neutrinos [PDF]

J.Phys.Conf.Ser.136:022043,2008, 2008
We review the prospects for probing new physics with neutrino astrophysics. High energy neutrinos provide an important means of accessing physics beyond the electroweak scale. Neutrinos have a number of advantages over conventional astronomy and, in particular, carry information encoded in their flavor degree of freedom which could reveal a variety of ...

Non-standard neutrino interactions mediated by a light scalar at DUNE

Journal of High Energy Physics
We investigate the effect on neutrino oscillations generated by beyond-the-standard-model interactions between neutrinos and matter. Specifically, we focus on scalar-mediated non-standard interactions (NSI) whose impact fundamentally differs from that of

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 ...

Final results of nu-e-bar electron scattering cross-section measurements and constraints on new physics

, 2012
The nu-e-bar electron elastic scattering cross-section was measured with a CsI(Tl) scintillating crystal detector array with a total mass of 187 kg at the Kuo-Sheng Nuclear Power Station. The detectors were exposed to a reactor nu-e-bar flux of 6.4 X 10^{

A plethora of long-range neutrino interactions probed by DUNE and T2HK

Journal of High Energy Physics
Upcoming neutrino experiments will soon search for new neutrino interactions more thoroughly than ever before, boosting the prospects of extending the Standard Model. In anticipation of this, we forecast the capability of two of the leading long-baseline

Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter

Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT Recent observational results, such as those from pulsar timing arrays (PTA), suggest a low‐frequency Gravitational Wave Background (GWB) permeates our universe. This opens the possibility that gravitational waves could span a broader spectrum, potentially impacting cosmological scales.
