Measurement of the absolute differential cross section of proton–proton elastic scattering at small angles
Abstract The differential cross section for proton–proton elastic scattering has been measured at a beam kinetic energy of 1.0 GeV and in 200 MeV steps from 1.6 to 2.8 GeV for centre-of-mass angles in the range from 12°–16° to 25°–30°, depending on...

Pure gravity mediation and spontaneous B–L breaking from strong dynamics
Abstract In pure gravity mediation (PGM), the most minimal scheme for the mediation of supersymmetry (SUSY) breaking to the visible sector, soft masses for the standard model gauginos are generated at one loop rather than via direct couplings to the ...

Pre-Hawking radiation may allow for reconstruction of the mass distribution of the collapsing object
Abstract Hawking radiation explicitly depends only on the black hole's total mass, charge and angular momentum. It is therefore generally believed that one cannot reconstruct the information about the initial mass distribution of an object that made ...

Magnetic moment, vorticity-spin coupling and parity-odd conductivity of chiral fermions in 4-dimensional Wigner functions
Abstract We demonstrate the emergence of the magnetic moment and spin-vorticity coupling of chiral fermions in 4-dimensional Wigner functions. In linear response theory with space–time varying electromagnetic fields, the parity-odd part of the...

Minimal asymmetric dark matter
Abstract In the early Universe, any particle carrying a conserved quantum number and in chemical equilibrium with the thermal bath will unavoidably inherit a particle–antiparticle asymmetry. A new particle of this type, if stable, would represent a...

Quark–hadron duality constraints on γZ box corrections to parity-violating elastic scattering
Abstract We examine the interference γZ box corrections to parity-violating elastic electron–proton scattering in the light of the recent observation of quark–hadron duality in parity-violating deep-inelastic scattering from the deuteron, and the...

An above-barrier narrow resonance in 15F
Abstract Intense and purified radioactive beam of post-accelerated 14O was used to study the low-lying states in the unbound 15F nucleus. Exploiting resonant elastic scattering in inverse kinematics with a thick target, the second excited state, a...

Fragment shapes in impact experiments ranging from cratering to catastrophic disruption
Abstract Laboratory impact experiments have found that impact fragments tend to be elongated. Their shapes, as defined by axes a, b and c, these being the maximum dimensions of the fragment in three mutually orthogonal planes (a ...

750 GeV diphotons from closed string states
Abstract We show that low-mass-scale string compactifications, with a generic D-brane configuration that realizes the standard model by open strings, can explain the relatively broad peak in the diphoton invariant mass spectrum at 750 GeV recently...

What we can learn from the spectral index of the tensor mode
Abstract If the beginning of inflation is defined at the moment when the vacuum energy of the inflaton starts to dominate, the energy density of the other fields at that moment is (by definition) comparable to the inflaton. Although the fraction...

Evaluation of momentum flux with radar
Abstract The statistics of gravity wave momentum flux estimation are investigated using data from the MU radar at Shigariki, Japan (136°E, 35°N). The radar has been operating during campaign periods since 1986. The first part of the paper focuses on ...

Radiative corrections to the Higgs boson couplings in the model with an additional real singlet scalar field
Abstract We calculate renormalized Higgs boson couplings with gauge bosons and fermions at the one-loop level in the model with an additional isospin singlet real scalar field. These coupling constants can deviate from the predictions in the...

Zeroth order phase transition in a holographic superconductor with single impurity
Abstract We investigate the single normal impurity effect in a superconductor by the holographic method. When the size of impurity is much smaller than the host superconductor, we can reproduce the Anderson theorem, which states that a conventional...

Hyperscaling violation and electroweak symmetry breaking
Abstract We consider a class of simplified models of dynamical electroweak symmetry breaking built in terms of their five-dimensional weakly-coupled gravity duals, in the spirit of bottom-up holography. The sigma-model consists of two abelian gauge...

Possible large CP violation in three-body decays of heavy baryon
Abstract We propose a new mechanism which can introduce large CP asymmetries in the phase spaces of three-body decays of heavy baryons. In this mechanism, a large CP asymmetry is induced by the interference of two intermediate resonances, which...
