Longitudinal double-spin asymmetries for dijet production at intermediate pseudorapidity in polarized pp collisions at s=200 GeV / Adam, J. ; Adamczyk, L. ; Adams, J. R. ; Adkins, J. K. ; et al
We present the first measurements of the longitudinal double-spin asymmetry ALL for dijets with at least one jet reconstructed within the pseudorapidity range 0.8<η<1.8. [...]

Unitarity of loop diagrams for the ghostlike 1/(k2M12)1/(k2M22) propagator / Mannheim, Philip D.
With fourth-order derivative theories leading to propagators of the generic ghostlike 1/(k2M12)1/(k2M22) form, it would appear that such theories have negative norm ghost states and are not unitary. [...]

Search for top squarks decaying to tau sleptons in pp collisions at s=13 TeV with the ATLAS detector / Aaboud, M. ; Aad, G. ; Abbott, B. ; Abdinov, O. ; et al
A search for direct pair production of top squarks in final states with two tau leptons, b-jets, and missing transverse momentum is presented. [...]

Electroweak dark matter at future hadron colliders / Han, Tao ; Mukhopadhyay, Satyanarayan ; Wang, Xing
In a large class of scenarios, dark matter (DM) particles that belong to a multiplet of the standard model (SM) weak interactions are challenging to probe in direct detection experiments due to loop-suppressed cross sections. [...]

Measuring CP violation in bcτν¯τ using excited charm mesons / Aloni, Daniel ; Grossman, Yuval ; Soffer, Abner
There is growing evidence for deviation from the standard model predictions in the ratios between semitauonic and semileptonic B decays, known as the R(D(*)) puzzle. [...]

Reappraisal of constraints on Z models from unitarity and direct searches at the LHC / Bandyopadhyay, Triparno ; Bhattacharyya, Gautam ; Das, Dipankar ; Raychaudhuri, Amitava
In a truly model-independent approach, we reexamine a minimal extension of the Standard Model (SM) through the introduction of an additional U(1) symmetry leading to a new neutral gauge boson (Z), allowing its kinetic mixing with the hypercharge gauge boson. [...]

Light scalar dark matter extension of the type-II two-Higgs-doublet model / Wang, Lei ; Shi, Rongle ; Han, Xiao-Fang ; Zhu, Bin
We examine the type-II two-Higgs-doublet model with a light scalar dark matter (S) after imposing the constraints from the Higgs searches at the LHC and dark matter experiments. [...]
