Convoluted ν‐Signals on 114Cd Isotope from Astrophysical and Laboratory Neutrino Sources

open access: yesAdvances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015
At first, we evaluate scattering cross sections of low, and intermediate‐energy neutrinos scattered off the 114 Cd isotope, the most abundant Cd isotope present also in the COBRA detector (CdTe and CdZnTe materials) which aims to search for double beta decay events and neutrino observations at Gran Sasso laboratory (LNGS).

Light scalars and dark photons in Borexino and LSND experiments

open access: yesPhysics Letters B, 2018
Bringing an external radioactive source close to a large underground detector can significantly advance sensitivity not only to sterile neutrinos but also to “dark” gauge bosons and scalars. Here we address in detail the sensitivity reach of the Borexino-

Seasonal Variations of the 7Be Solar Neutrino Flux

open access: yes, 1999
Measuring the 7Be solar neutrino flux is crucial towards solving the solar neutrino puzzle. The Borexino experiment, and possibly the KamLAND experiment, will be capable of studying the 7Be neutrinos in the near future.

Comprehensive geoneutrino analysis with Borexino [PDF]

open access: yesPhysical Review D, 2019
This paper presents a comprehensive geoneutrino measurement using the Borexino detector, located at Laboratori Nazionali del Gran Sasso (LNGS) in Italy. The analysis is the result of 3262.74 days of data between December 2007 and April 2019.

Solar neutrino results from Borexino

open access: greenNuclear Physics B - Proceedings Supplements, 2013
Abstract Borexino is a large-volume liquid scintillator experiment for low energy neutrino detection, operating since May 2007, and installed at the National Laboratory of Gran Sasso. Borexino is the first experiment able to observe in real-time Solar neutrino interactions also in the sub-MeV range.

Detecting dark photons from atomic rearrangement in the galaxy

open access: yesJournal of High Energy Physics, 2021
We study a new dark sector signature for an atomic process of “rearrangement” in the galaxy. In this process, a hydrogen-like atomic dark matter state together with its anti-particle can rearrange to form a highly-excited bound state.

New experimental limits on the Pauli forbidden transitions in $^{12}$C nuclei obtained with 485 days Borexino data

open access: yes, 2009
The Pauli exclusion principle (PEP) has been tested for nucleons ($n,p$) in $^{12}C$ with the Borexino detector.The approach consists of a search for $\gamma$, $n$, $p$ and $\beta^\pm$ emitted in a non-Paulian transition of 1$P_{3/2}$- shell nucleons to ...

Short distance neutrino oscillations with Borexino

open access: yesEPJ Web of Conferences, 2016
The Borexino detector has convincingly shown its outstanding performances in the low energy, sub-MeV regime through its unprecedented accomplishments in the solar and geo-neutrinos detection.

Light vector mediators facing XENON1T data

open access: yesPhysics Letters B, 2020
Recently the XENON1T collaboration has released new results on searches for new physics in low-energy electronic recoils. The data shows an excess over background in the low-energy tail, particularly pronounced at about 2−3keV.

New limits on heavy sterile neutrino mixing in ${^{8}\rm{B}}$-decay obtained with the Borexino detector

open access: yes, 2013
If heavy neutrinos with mass $m_{\nu_{H}}\geq$2$ m_e $ are produced in the Sun via the decay ${^8\rm{B}} \rightarrow {^8\rm{Be}} + e^+ + \nu_H$ in a side branch of pp-chain, they would undergo the observable decay into an electron, a positron and a light
