2021/06/21: New T2K oscillation paper with Liverpool / VALOR contribution
A new T2K oscillation paper describing a joint 3-flavour analysis of both
muon-neutrino disappearance and electron-neutrino appearance channels
using all neutrino and antineutrino T2K data in Runs 1-9), has been published in
Phys.Rev.D 103 (2021) 11, 112008.
This is a longer version of the analysis published in
Nature volume 580, pages 339–344 (2020).
Our PhD student Francis Bench participated in the
paper committee, as this published work included results from the
VALOR neutrino oscillation analysis
with contributions from several members of our group.

2021/06/18: New GENIE paper highlighting recent v3 developments
A new paper highlighting recent developments in the the well-known
GENIE event generator is now
posted at the arXiv (e-print: 2106.09381 [hep-ph]).

2021/06/16: New GENIE paper on neutrino-induced hadronic multiparticle model tuning

Julia Tena-Vidal is now
posted at the arXiv (e-print: 2106.05884 [hep-ph]).
It presents a new tune of the
Andreopoulos-Gallagher-Kehayias-Yang (AGKY) hadronization model in GENIE

2021/04/21: New GENIE paper on neutrino-nucleon cross-section model tuning
A new paper summarising the new neutrino-nucleon cross-section model tunes installed in
the well-known GENIE event generator is now
posted at the arXiv (e-print: 2104.09179 [hep-ph]).
The new tunes improve the cross-section modelling of low-multiplicity inelastic channels (single-pion and double-pion production)
and the modelling of the relative contributions of resonance and non-resonance processes to these final states.
Our PhD student Julia Tena-Vidal was the lead analyzer and first author.
Julia is funded through the Liverpool LIV.DAT
CDT on data intensive sciences with a project to develop physics simulation to underpin discoveries in the neutrino sector.
This is the first publication using the GENIE/Professor tuning interface developed by Liverpool post-doc
Marco Roda.
Initial work was supported by a Durham IPPP associateship award.

(Click here for the scientific program.)
Two members of the group gave excellent and well-received talks there:
Marco Roda
gave an overview of the
GENIE tuning efforts,
while
Julia Tena-Vidal

2020/12/01: Successful completion of our European Space Agency funded POSITRINO project
On December 1st, Costas Andreopoulos, Chris Barry,
Marco Roda and Júlia Tena Vidal
participated in the final review of the POSITRINO project. This is a European Space Agency (ESA) funded project for a
preliminary exploration of the innovative and disrupting technological concept of Positioning, Navigation and Timing (PNT)
applications based on neutrinos.
In this project, Liverpool teamed up with
Ana Cezón Moro, Javier Fidalgo Prieto, Stefano Melis and others from
GMV Innovations, a technological
business group headquartered in Madrid, with leading presence in many sectors including Defence and Security, Space, and Aeronautics.
The project was aimed at applications where the Global Navigation Satellite System (GNSS) cannot work, such as
i) submarine navigation, ii) navigation in the Earth poles, where no GNSS satellites are in view, or iii) sub-surface applications.
Submarine navigation was chosen as the benchmark application due to the obvious disrupting potential:
Using neutrinos for navigation, in conjunction with other sensors, would allow military nuclear submarines to remain submerged,
in stealth mode, for very long times.
The final review was attended by several key figures in the field of including the Head of ESA GNNS Strategy,
as well as German, Italian and Czech state delegates to ESA.
According to Florin Grec overseeing this work on behalf of ESA along with Luis Mendes,
“The final outcome of the project surpassed our expectations and we are very pleased by the work done by GMV and Liverpool”.
Details will appears in a future publication.

2020/02/05: CERN Theory Colloquium by Prof. Andreopoulos
In
a talk presented at the CERN Theory Colloquium,

discussed the significance of improving our understanding of neutrino-nucleus interactions
and highlight some of the most pertinent puzzles in neutrino interaction physics,
and emphasised open problems in neutrino interaction phenomenology.

important issues with a CERN audience.

2020/01/08-10: Contributions to the Fermilab Generator Tools Workshop
Early in January 2020, Costas Andreopoulos and,
Marco Roda attended the
Fermilab Generator Tools Workshop,
representing the GENIE collaboration
which is responsible for a suite of successful and very popular physics simulations and toolkits
incorporated into the simulation and analysis chain of many neutrino experiments.
Costas
discussed proposals, on behalf
of the GENIE collaboration, that would enable experiments to reuse their well-established
workflows and GENIE interfaces and toolkits (event generation, flux and detector
geometry drivers) in order to run a host of alternative physics simulations
that are development by smaller groups and lack the extensive toolkit present in GENIE.
The proposal, exemplifies the key role of the GENIE group in supporting the development
of physics simulations for the experimental neutrino community:
It would produce significant effiencies in delivering alternative physics simulations into
the full simulation chain of modern experiments, removing the need for duplication of
very extensive toolkits, and allowing developers to focus on the most crucial aspects of physics modelling.
