Abstract Young diagrams can be parameterized with the help of hook variables, which is well known, but never studied in big detail. We demonstrate that this is the most adequate parameterization for many physical applications: from the Schur functions, conventional, skew and shifted, which all satisfy their own kinds of determinant formulas in these coordinates, to KP/Toda integrability and related basis of cut-and-join W ˆ -operators, which are both actually expressed through the single-hook di...

Abstract We consider the effect of higher twist operators of the Wilson operator product expansion in the structure function F 2 ( x , Q 2 ) at small-x, taking into account QCD effective charges whose infrared behavior is constrained by a dynamical mass scale. The higher twist corrections are obtained from the renormalon formalism. Our analysis is performed within the conventional framework of next-to-leading order, with the factorization and renormalization scales chosen to be Q 2 . The infrare...

Abstract We consider the search for axion-like particles (ALPs) by using time series data of the polarization angle of the light. If the condensation of an ALP plays the role of dark matter, the polarization plane of the light oscillates as a function of time and we may be able to detect the signal of the ALP by continuously observing the polarization. In particular, we discuss that the analysis of the Fourier-transformed data of the time-dependent polarization angle is powerful to find the sign...

Abstract A set of equations of state obtained from finite-range Gogny forces and momentum-dependent interactions is used to investigate the recent observation of gravitational waves from the binary neutron star merger GW170817 event. For this set of interactions, we have calculated the neutron star tidal deformabilities (related to the second Love number), the mass-radius diagram, and the moment of inertia (I). The I-Love relation has been verified. We also have found strong correlations among t...

Abstract Two new families of nonlinearly charged and asymptotically anti-de Sitter (AdS) rainbow black holes have been introduced, as the exact solutions to the coupled electromagnetic and gravitational field equations, in massive gravity theory and in the presence of power-law nonlinear electrodynamics. The conserved and thermodynamic quantities such as black hole mass, charge, temperature, entropy and electric potential have been calculated from geometric and thermodynamic approaches. Despite ...

Abstract It is shown that Kazama-Suzuki conditions for the denominator subgroup of N = 2 superconformal G / H coset model determine Generalized Kahler geometry on the target space of the corresponding N = 2 supersymmetric σ-model.

In this paper, we analytically study the phase structure and construct the Ruppeiner geometry in the extended phase space for the five-dimensional neutral Gauss-Bonnet AdS black hole. Through calculating the scalar curvature of the Ruppeiner geometry and combining the phase transition, we show that the attractive interaction is dominant in the microstructure of the black hole system. More significantly, there is an intriguing property that the normalized scalar curvature has the same expression ...

Abstract In this letter we show that the two parton showers mechanism for J / Ψ production, that has been discussed in Ref. [23] , leads to small values of σ eff for the production of a pair of J / Ψ . We develop a simple two channel approach to estimate the values of σ eff , which produces values that are in accord with the experimental data.

Abstract We show that axion models with the domain wall number k in ( 3 + 1 ) dimensions, i.e., periodic scalar field theories admitting k axion domain walls, exhibit an emergent Z k 3-form symmetry for k > 1 in addition to a conventional Z k 0-form symmetry. The emergent 3-form symmetry is explicitly shown by establishing a low-energy dual transformation between the scalar field theory and a 3-form gauge theory. We further argue that the emergent 3-form symmetry is spontaneously broken, and the...

Abstract The transverse momentum ( p T ) spectra of inclusively produced Λ c + baryons are measured via the exclusive decay channel Λ c + → p K − π + using the CMS detector at the LHC. Spectra are measured as a function of transverse momentum in proton-proton ( p p ) and lead-lead (PbPb) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The measurement is performed within the Λ c + rapidity interval | y | 1 in the p T range of 5–20 GeV/ c in p p and 10–20 GeV/ c in PbPb collisio...
