Superstatistics and the effective QCD phase diagram / Ayala, Alejandro ; Hentschinski, Martin ; Hernández, L. A. ; Loewe, M. ; et al
We study the effect of a partially thermalized scenario for chiral symmetry restoration at finite temperature and quark chemical potential, and in particular for the position of the critical end point in an effective description of the QCD phase diagram. [...]

Chiral phase transition with 2+1 quark flavors in an improved soft-wall AdS/QCD model / Fang, Zhen ; Wu, Yue-Liang ; Zhang, Lin
We study the chiral phase transition with 2+1 quark flavors in an improved soft-wall AdS/QCD model, which can produce the light meson spectrum and many other low-energy quantities consistent with experiments in the two-flavor case. [...]

Freeze-in dark matter from a sub-Higgs mass clockwork sector via the Higgs portal / Kim, Jinsu ; McDonald, John
The clockwork mechanism allows extremely weak interactions and small mass scales to be understood in terms of the structure of a theory. [...]

Beyond R(D(*)) with the general type-III 2HDM for bcτν / Martinez, R. ; Sierra, C. F. ; Valencia, German
We review the parameter regions allowed by measurements of R(D(*)) and by a theoretical limit on B(Bcτν) in terms of generic scalar and pseudoscalar new physics couplings, gs and gp. [...]

P-wave contributions to Bψππ decays in the perturbative QCD approach / Rui, Zhou ; Li, Ya ; Li, Hsiang-nan
We present the differential branching fractions for the Bψππ decays with the charmonia ψ=J/ψ,ψ(2S) in the invariant mass of the P-wave pion pairs in the perturbative QCD approach. [...]

Combined explanations of (g2)μ,e and implications for a large muon EDM / Crivellin, Andreas ; Hoferichter, Martin ; Schmidt-Wellenburg, Philipp
With the long-standing tension between experiment and standard-model (SM) prediction in the anomalous magnetic moment of the muon, aμ=(g2)μ/2, at the level of 34σ, it is natural to ask if there could be a sizable effect in the electric dipole moment (EDM) dμ as well. [...]

Supersymmetry and LHC missing energy signals / Carena, Marcela ; Osborne, James ; Shah, Nausheen R. ; Wagner, Carlos E. M.
Current analyses of the LHC data put stringent bounds on strongly interacting supersymmetric particles, restricting the masses of squarks and gluinos to be above the TeV scale. [...]

Anatomy of a strong residual sign problem on the thimbles / Bloch, Jacques
Using a simple Gaussian-like Ansatz for the phase distribution of a theory with a complex action, we show how the thimble integration for the average phase factor can be plagued by a strong residual sign problem when the phase of the complex integration measure conspires with the constant phase of the integrand along the thimble.

The dark axion portal is a recently introduced portal between the standard model and the dark sector. [...]
