Sensitivity to CP Discovery in the Presence of Lorentz Invariance Violating Potential at T2HK/T2HKK
Supriya Pan, Kaustav Chakraborty, Srubabati Goswami
Investigation of conservation/violation of CP symmetry in the leptonic sector is very essential in understanding the evolution of the universe. Lorentz invariance and CPT are funda…
Analytic treatment of 3-flavor neutrino oscillation and decay in matter
Dibya S. Chattopadhyay, Kaustav Chakraborty, Amol Dighe +1
We present compact analytic expressions for 3-flavor neutrino oscillation probabilities with invisible neutrino decay, where matter effects have been explicitly included. We take i…
Snowmass White Paper: Beyond the Standard Model effects on Neutrino Flavor
C. A. Argüelles, G. Barenboim, M. Bustamante +23
Neutrinos are one of the most promising messengers for signals of new physics Beyond the Standard Model (BSM). On the theoretical side, their elusive nature, combined with their un…
Neutrino propagation when mass eigenstates and decay eigenstates mismatch
Dibya S. Chattopadhyay, Kaustav Chakraborty, Amol Dighe +2
We point out that the Hermitian and anti-Hermitian components of the effective Hamiltonian for decaying neutrinos cannot be simultaneously diagonalized by unitary transformations f…
Constraining general U(1) interactions from neutrino-electron scattering measurements at DUNE near detector
Kaustav Chakraborty, Arindam Das, Srubabati Goswami +1
The neutrino-electron scattering process is a powerful tool to explore new physics beyond the standard model. Recently the possibility of DUNE Near Detector (ND) to constrain vario…
Invisible neutrino decay : First vs second oscillation maximum
Kaustav Chakraborty, Debajyoti Dutta, Srubabati Goswami +1
We study the physics potential of the long-baseline experiments T2HK, T2HKK and ESSSB in the context of invisible neutrino decay. We consider normal mass ordering and assume tha…
New physics at nuSTORM
Kaustav Chakraborty, Srubabati Goswami, Kenneth Long
In this work we investigate the usefulness of nuSTORM as a probe of two new-physics scenarios which are sterile neutrinos and non-unitarity of the neutrino mixing matrix. For the s…
Consequences of - reflection symmetry for neutrino mixing
Kaustav Chakraborty, Srubabati Goswami, Biswajit Karmakar
We investigate the consequences of reflection symmetry in presence of a light sterile neutrino for the neutrino mixing scheme. We discuss the implications of total $μ-τ…
Enhancing the hierarchy and octant sensitivity of ESSSB in conjunction with T2K, NOA and ICAL@INO
Kaustav Chakraborty, Srubabati Goswami, Chandan Gupta +1
The main aim of the ESSSB proposal is the discovery of the leptonic CP phase with a high significance ( for 50% values of ) by utilizing the physics at the…
Exploring Partial - Reflection Symmetry at DUNE and Hyper-Kamiokande
Kaustav Chakraborty, K. N. Deepthi, Srubabati Goswami +2
We study origin, consequences and testability of a hypothesis of `partial -' reflection symmetry. This symmetry predicts for a single column o…
Spotlighting the sensitivities of T2HK,T2HKK and DUNE
Kaustav Chakraborty, K. N. Deepthi, Srubabati Goswami
Neutrino oscillation physics has entered the precision era and the potential forthcoming experiments Hyper-Kamiokande and Deep Under-ground Neutrino Experiment (DUNE) are expected…
