TL;DR: In this article, the authors explore the possibility that a broad spectrum of primordial black holes is formed in models of Critical Higgs Inflation (CHI), where the near-inflection point is related to the critical value of the RGE running of both the Higgs self-coupling and its non-minimal coupling to gravity.

TL;DR: In this article, the authors combine new analysis of the stochastic gravitational wave background to be expected from cosmic strings with the latest pulsar timing array (PTA) limits to give an upper bound on the energy scale of the possible cosmic string network, G μ 1.5 × 10 − 11 at the 95% confidence level.

TL;DR: In this paper, the authors propose soft photon emission by light dark matter as a natural solution to the 21 cm anomaly, and find that the signal singles out a photophilic dark matter candidate characterized by an enhanced collective decay mechanism, such as axion mini-clusters.

TL;DR: In this paper, the moments of the net-kaon multiplicity distributions in relativistic heavy-ion collisions were measured and compared with Poisson and negative binomial baseline calculations as well as with UrQMD.

TL;DR: In this article, the authors employed a Bayesian neural network (BNN) approach to improve the nuclear mass predictions of various models and found that the noise error in the likelihood function plays an important role in the predictive performance of the BNN approach.

TL;DR: In this paper, the angular distribution of the decay B0→K ⊆ 0μ+μ− is studied using a sample of proton-proton collisions at s=8TeV collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 20.5fb−1.

TL;DR: In this article, it was shown that the kite integral family can be solved in e-form if the Feynman integrals do not evaluate to multiple polylogarithms.

TL;DR: The concept of effective dynamics has proven successful in LQC, a loop-inspired quantization of cosmological spacetimes, by computing the expectation value of the scalar constraint with respect to some coherent states peaked on the phase-space variables of flat Robertson-Walker spacetime.

TL;DR: In this paper, a model of quark-lepton unification at the TeV scale based on an S U ( 4 ) gauge symmetry was constructed, while still having acceptable neutrino masses and enough suppression in flavor changing neutral currents.

TL;DR: This article showed that Rastall gravity is completely equivalent to the usual general relativity, and that the gravity sector is completely standard, based as usual on the Einstein tensor, while the matter sector corresponds to an artificially isolated part of the physical conserved stress energy.
