Review of particle physics
/ Particle Data Group Collaboration
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,717 new measurements from 869 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons [...]

The effect of outflows on CMB bounds from Primordial Black Hole accretion
/ Piga, Lorenzo (Parma U. ; INFN, Parma) ; Lucca, Matteo (Brussels U.) ; Bellomo, Nicola (Texas U., TCC) ; Bosch-Ramon, Valentì (ICC, Barcelona U.) ; Matarrese, Sabino (U. Padua, Dept. Phys. Astron. ; INFN, Padua ; Padua Observ. ; GSSI, Aquila) ; Raccanelli, Alvise (U. Padua, Dept. Phys. Astron. ; INFN, Padua ; Padua Observ. ; CERN) ; Verde, Licia (ICC, Barcelona U. ; ICREA, Barcelona)
Should Primordial Black Holes (PBHs) exist in nature, they would inevitably accrete baryonic matter in their vicinity. In turn, the consequent emission of high-energy radiation could affect the thermal history of the universe to an extent that can be probed with a number of cosmological observables such as the Cosmic Microwave Background (CMB) anisotropies.

Beware of commonly used approximations : Part I. Errors in forecasts
/ Bellomo, Nicola (Barcelona, IEEC ; Barcelona U., Dept. Fund. Phys.) ; Bernal, José Luis (Johns Hopkins U. ; Barcelona, IEEC ; Barcelona U., Dept. Fund. Phys.) ; Scelfo, Giulio (SISSA, Trieste ; INFN, Trieste ; IFPU, Trieste ; Padua U. ; Padua U., Astron. Dept. ; Barcelona, IEEC) ; Raccanelli, Alvise (CERN ; Barcelona, IEEC) ; Verde, Licia (Barcelona, IEEC ; ICREA, Barcelona)
In the era of precision cosmology, establishing the correct magnitude of statistical errors in cosmological parameters is of crucial importance. However, widely used approximations in galaxy surveys analyses can lead to parameter uncertainties that are grossly mis-estimated, even in a regime where the theory is well understood (e.g., linear scales). [...]

Prospects for Fundamental Physics with LISA
/ LISA Collaboration
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental physics. Given the very broad range of topics that might be relevant to LISA, we present here a sample of what we view as particularly promising directions, based in part on the current research interests of the LISA scientific community in the area of fundamental physics. [...]

Enlightening the dark ages with dark matter
/ Short, Katie (ICC, Barcelona U. ; Barcelona, IEEC) ; Bernal, José Luis (Johns Hopkins U. (main) ; ICC, Barcelona U. ; Barcelona, IEEC) ; Raccanelli, Alvise (CERN ; ICC, Barcelona U. ; Barcelona, IEEC) ; Verde, Licia (ICC, Barcelona U. ; Barcelona, IEEC ; Jodrell Bank ; U. Manchester (main)) ; Chluba, Jens (ICREA, Barcelona)
Constraints on dark matter annihilation or decay offer unique insights into the nature of dark matter. We illustrate how surveys dedicated to detect the highly redshifted 21 cm signal from the dark ages will offer a new window into properties of particle dark matter. [...]

From Primordial Black Holes Abundance to Primordial Curvature Power Spectrum (and back)
/ Kalaja, Alba (Padua U., Astron. Dept. ; ICC, Barcelona U. ; U. Groningen, VSI) ; Bellomo, Nicola (ICC, Barcelona U. ; U. Barcelona (main)) ; Bartolo, Nicola (Padua U., Astron. Dept. ; INFN, Padua ; Padua Observ.) ; Bertacca, Daniele (Padua U., Astron. Dept. ; INFN, Padua) ; Matarrese, Sabino (Padua U., Astron. Dept. ; INFN, Padua ; Padua Observ. ; GSSI, Aquila) ; Musco, Ilia (ICC, Barcelona U.) ; Raccanelli, Alvise (ICC, Barcelona U. ; CERN) ; Verde, Licia (ICC, Barcelona U. ; ICREA, Barcelona)
In the model where Primordial Black Holes (PBHs) form from large primordial curvature (C) perturbations, i.e., CPBHs, constraints on PBH abundance provide in principle constraints on the primordial curvature power spectrum. This connection however depends necessarily on the details of PBH formation mechanism. [...]

BE-HaPPY: Bias Emulator for Halo Power Spectrum including massive neutrinos
/ Valcin, David (ICC, Barcelona U.) ; Villaescusa-Navarro, Francisco (Flatiron Inst., New York) ; Verde, Licia (ICC, Barcelona U. ; ICREA, Barcelona) ; Raccanelli, Alvise (ICC, Barcelona U. ; CERN)
We study the clustering properties of dark matter halos in real- and redshift-space in cosmologies with massless and massive neutrinos through a large set of state-of-the-art N-body simulations. We provide quick and easy-to-use prescriptions for the halo bias on linear and mildly non-linear scales, both in real and redshift space, which are valid also for massive neutrinos cosmologies. [...]
