Remark on the open string pair production enhancement / Jia, Qiang ; Lu, J.X.
Recent studies by one of the present authors along with his collaborators in [1–4] show that there exist the so-called open string pair production for a possible simplest system of two Dp branes, placed parallel at a separation and with each carrying different electric flux, in Type II superstring theories. [...]

Revisiting Ds0⁎(2317) as a 0 + tetraquark state from QCD sum rules / Zhang, Jian-Rong
Stimulated by the renewed observation of Ds0⁎(2317) signal and its updated mass value 2318.3±1.2±1.2MeV/c2 in the process e+e−→Ds⁎+Ds0⁎(2317)−+c.c. [...]

Measurement of the beam spin asymmetry of e→p→e′p′η in the deep-inelastic regime with CLAS / Zhao, B. ; Kim, A. ; Joo, K. ; Bedlinskiy, I. ; et al
The beam spin asymmetry of the exclusive pseudoscalar channel e→p→e′p′η was measured for the first time in the deep-inelastic regime ( W>2 GeV/c2 and Q2>1 GeV2/c2 ) using a longitudinally polarized 5.78 GeV electron beam at Jefferson Lab with the CEBAF Large Acceptance Spectrometer. [...]

Search for Abelian dominance in the effective SO ( N ) theory / Raval, Haresh
Recently a new quadratic gauge has been introduced in the SU(N) QCD in which interesting non perturbative characteristics of QCD has been brought to light. [...]

GUT scale unification in heterotic strings / Angelantonj, Carlo ; Florakis, Ioannis
We present a class of heterotic compactifications where it is possible to lower the string unification scale down to the GUT scale, while preserving the validity of the perturbative analysis. [...]

Blue and violet graviton spectra from a dynamical refractive index / Giovannini, Massimo
We show that the spectral energy distribution of relic gravitons mildly increases for frequencies smaller than the μHz and then flattens out whenever the refractive index of the tensor modes is dynamical during a quasi-de Sitter stage of expansion. [...]

Constraining R-axion models through dijet searches at the LHC / Arganda, Ernesto ; Medina, Aníbal D. ; Mileo, Nicolás I. ; Morales, Roberto A. ; et al
The search at hadron colliders for new massive resonances of a few 100 GeVs that couple effectively to colored states is an extremely challenging issue, due principally to the presence of large QCD multijet backgrounds at this energy, rendering the searches at the LHC particularly difficult. [...]

Constraining resonant dark matter with combined LHC electroweakino searches / Pozzo, Giancarlo ; Zhang, Yang
In the Minimal Supersymmetric Standard Model light neutralinos can satisfy the dark matter (DM) abundance constraint by resonant annihilation via a Z or a light Higgs ( h ) boson. [...]
