Constraining visible neutrino decay at KamLAND and JUNO

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We study visible neutrino decay at the reactor neutrino experiments KamLAND and, JUNO. Assuming the Majoron model of neutrino decay, we obtain constraints on the couplings between Majoron and neutrino as well as on the lifetime/mass of the most massive ...

Reduced Density Matrix Cumulants: The Combinatorics of Size-Consistency and Generalized Normal Ordering.

open access: yesJournal of Chemical Theory and Computation, 2020
Reduced density matrix cumulants play key roles in the theory of both reduced density matrices and multiconfigurational normal ordering. We present a new, simpler generating function for reduced density matrix cumulants that is formally identical to ...

Combined sensitivity of JUNO and KM3NeT/ORCA to the neutrino mass ordering

open access: yesJournal of High Energy Physics, 2022
This article presents the potential of a combined analysis of the JUNO and KM3NeT/ORCA experiments to determine the neutrino mass ordering. This combination is particularly interesting as it significantly boosts the potential of either detector, beyond ...

Continuous review inventory model with lost sale reduction and ordering cost dependent on lead time for the mixtures of distributions [PDF]

open access: yesYugoslav Journal of Operations Research, 2021
We consider a continuous review inventory system for inventory model involving lost sales reduction through capital investment cost function and the reduction of lead time further which reduces the ordering cost.

Higher-Order Orderings for Normal Rewriting [PDF]

open access: yes, 2006
We extend the termination proof methods based on reduction orderings to higher-order rewriting systems a la Nipkow using higher-order pattern matching for firing rules, and accommodate for any use of eta, as a reduction, as an expansion or as an equation.

A normal form for spider diagrams of order [PDF]

open access: yesJournal of Visual Languages & Computing, 2014
We develop a reasoning system for an Euler diagram based visual logic, called spider diagrams of order. We de- fine a normal form for spider diagrams of order and provide an algorithm, based on the reasoning system, for producing diagrams in our normal form.

A note on normal ordering of degenerate integral powers of number operator [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
This study derives the normal ordering expansion of degenerate integral powers of the number operator, (a†a)_{n,λ}, using recurrence relations for the coefficients and an operator action on number states. Here a† and a are respectively the boson creation

SN1987A and neutrino non-radiative decay

open access: yesPhysics Letters B, 2023
We investigate neutrino non-radiative two-body decay in vacuum, in relation to SN1987A. In a full 3ν decay framework, we perform a detailed likelihood analysis of the 24 neutrino events from SN1987A observed by Kamiokande-II, IMB, and Baksan. We consider

Status of neutrino oscillations 2018: 3σ hint for normal mass ordering and improved CP sensitivity [PDF]

open access: yesPhysics Letters B, 2017
We present a new global fit of neutrino oscillation parameters within the simplest three-neutrino picture, including new data which appeared since our previous analysis [1] .
