The W boson mass plays a crucial role as one of the most significant electroweak precision observables for scrutinizing the Standard Model and it is potential extensions. Recent measurements of the W boson mass at CDF indicate an extraordinary deviation of about 7σ from the SM predicted value, raising questions about the internal consistency of the model.
In this work, we investigate the...
This study was aimed at determining theoretically the parameter from the sum of neutrino masses as predicted using the quantum gravitational couplings/effective Majorana dimensionless coupling from the spherical symmetry vacuum solution. A seesaw mechanism (ala mode matrix) was adopted; where the SU matrix was diagonalized to get the mass eigen states. The parameter which is expressed as a...
This research delves into the influence of intrinsic decoherence on the
behavior of quantum correlations and coherence between two interacting qubits in a
graphene-based system. To evaluate the amount of nonclassical correlations in the
system, we employ local quantum uncertainty (LQU), and to assess quantum
coherence, we use the relative entropy of coherence (Cr) and l1-norm (Cl1)....
The nonzero neutrino masses open a door for neutrino electromagnetic interactions [1]. We study how these interactions may manifest themselves in elastic neutrino-nucleon scattering processes. Following our approach developed for the case of elastic neutrino-electron [2] and neutrino-proton [3-5] collisions, in our formalism we account for possible electromagnetic form factors of massive...
Deep inelastic scattering on nucleons is the main process of interaction of high-energy neutrinos with matter. The corresponding cross sections are measured, for example, in the IceCube experiment on the basis of the dependence of the neutrino flux registered in the range 60 TeV - 10 PeV on the direction of its arrival in the detector [1]. This provides a unique opportunity to study the...
Hyper-Kamiokande is a new generation of deep underground neutrinos experiments expected to take data in 2027. The detector tank is 68 m in height and 71m in diameter, with a total volume of 258kt. The fiducial volume for neutrinos interactions is expected to be 180kt or greater, This is at least 8 times larger than SuperK. This will enhance the discovery of CP violation and nucleus decay....
We generalize our previous results on neutrino flavor and spin flavour oscillations
in an external magnetic field and arbitrary moving media accounting for neutrino
electromagnetic interaction [1-2]. We consider neutrino oscillations and evolution
accounting for: 1) the neutrino interaction with an external magnetic field through
neutrino magnetic moment; 2) weak interaction with an...
The increase of the particle flux (pile-up) at the HL-LHC with instantaneous luminosities up to L ≃ 7.5 × 1034 cm−2s−1 will have a severe impact on the ATLAS detector reconstruction and trigger performance. The end-cap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has poorer momentum resolution will be particularly affected. A High...
We study theoretically the propagation of cosmic neutrinos in an interstellar magnetic field, which is known to have both constant and stochastic components. The neutrino interaction with a magnetic field is assumed to be due to a non-zero neutrino magnetic moment. For taking into account the effect of magnetic field fluctuations, the formalism of the Lindblad equation is employed that...
Superconducting charge qubits represent a cutting-edge technology in the field of quantum
computing. This study delves into the behaviors of thermal coherence and quantum correlations
within a two-superconducting charge qubit system coupled by a fixed capacitance. Specifically, we
investigate the effects of thermal noise on entanglement, nonclassical correlations, and quantum
coherence...
The effect of neutrino quantum decoherence has been studied actively in recent years (see [1-3] and references therein). In our present paper we consider the interaction with an arbitrary reservoir in thermodynamic equilibrium. We have found that within a fairly wide class of theoretical models the parameters of neutrino quantum decoherence are proportional to the neutrino decay rates into a...
Quantum-enhanced measurements exploit quantum mechanical effects for increasing the sensitivity of measurements of certain physical parameters and have great potential for both fundamental science and concrete applications. Most of the research has so far focused on using highly entangled states, which are, however, difficult to produce and to stabilize for a large number of constituents. In...
The existence of dark matter (DM) is carried by a variety of astrophysical measurements, however the nature and properties of the DM are still largely unidentified. The presence of DM is not predicted by the Standard Model (SM), but many theories beyond the Standard Model (BSM) offer the study of DM. Weakly Interacting Massive Particles (WIMPs, denoted as $\chi$) are frequently used as...
We investigate how bipartite entanglement and skew information correlations are affected by
intrinsic decoherence in a hybrid qubit-qutrit Heisenberg XXZ model that incorporates the
Dzyaloshinsky-Moriya interaction and is subject to the action of an external inhomogeneous
magnetic field. We employ local quantum uncertainty and uncertainty-induced nonlocality to
estimate skew information...
Based on the correspondence linking integrable superspin chain systems with internal symmetry described by a superalgebra to four-dimensional Chern-Simons gauge theory, we realize the sl(m|n) superspin chain model in terms of branes in Type IIA strings.
For this purpose, we study the presentation of four-dimensional topological line defects having super gauge symmetry in the higher...
The quest of a theory of quantum gravity has been a long journey for physicists, even after the introduction of string theory which has solved many problems on the matter. Recently the Swampland Program has made great progress, since it differentiates between what could be a theory of quantum gravity and what theories could not. This can be done by introducing some conditions, also known as...
This work delves into a comprehensive examination of the phase portrait and critical characteristics of a specific type of black hole solution, namely the Kerr-Newman-anti-de Sitter black hole. Our study takes into account the presence of two sources of energy. By considering the cosmological constant as an analog of thermodynamic pressure, we elucidate the essential methodologies employed to...
We consider the influence of quantum decoherence of neutrino mass states on collective neutrino oscillations in the supernova fluxes. Collective neutrino oscillations arise from the high density of neutrinos themselves which is the case in supernovae. In our work the neutrino system is considered as an open quantum system, taking into account the neutrino self-interaction. To study such a...
We investigate the dynamics of bipartite entanglement and nonclassical correlations in a dipole-dipole two-spin system subjected to the Dzyaloshinsky-Moriya (DM) interaction and the intrinsic decoherence. We consider that our system is initially prepared in a Werner state, and we study the effects of the intrinsic decoherence rate, the DM interaction, the dipolar coupling parameters and the...
