Probing homogeneity with standard candles
/ Chiang, Hsu Wen (Taiwan, Natl. Taiwan U.) ; Romano, Antonio Enea (CERN ; Antioquia U. ; Bishop's U., Sherbrooke) ; Nugier, Fabien (Taiwan, Natl. Taiwan U.) ; Chen, Pisin (Taiwan, Natl. Taiwan U. ; KIPAC, Menlo Park)
We show that standard candles can provide some valuable information about the density contrast, which could be particularly important at redshifts where other observations are not available. We use an inversion method to reconstruct the local radial density profile from luminosity distance observations assuming background cosmological parameters obtained from large scale observations.

The effect of anisotropic stress and non-adiabatic pressure perturbations on the evolution of the comoving curvature perturbation
/ Naruko, Atsushi (Tohoku U. ; Kyoto U., Yukawa Inst., Kyoto) ; Romano, Antonio Enea (Antioquia U. ; CERN ; Bishop's U., Sherbrooke) ; Sasaki, Misao (Kyoto U., Yukawa Inst., Kyoto ; Tokyo U., IPMU ; Taiwan, Natl. Taiwan U.) ; Vallejo-Peña, Sergio Andrés (Antioquia U.)
We derive the equation for the evolution of the curvature perturbation on the comoving time slice, $\mathcal{R}_c$, in the presence of anisotropic and non-adiabatic terms in the energy-momentum tensor of matter fields. The equation is obtained by manipulating the perturbed Einstein's equations in the comoving time slice. [...]

Gravitational waves from rapid structure formation on microscopic scales before matter-radiation equality
/ Flores, Marcos M. (UCLA) ; Kusenko, Alexander (UCLA ; Tokyo U., IPMU ; CERN) ; Sasaki, Misao (Tokyo U., IPMU ; Kyoto U., Yukawa Inst., Kyoto ; Taiwan, Natl. Taiwan U.)
The existence of scalar fields can be probed by observations of stochastic gravitational waves. Scalar fields mediate attractive forces, usually stronger than gravity, on the length scales shorter than their Compton wavelengths, which can be non-negligible in the early Universe, when the horizon size is small. [...]

Timing Performance of the CMS High Granularity Calorimeter Prototype
/ CMS HGCAL Collaboration
This paper describes the experience with the calibration, reconstruction and evaluation of the timing capabilities of the CMS HGCAL prototype in the beam tests in 2018. The calibration procedure includes multiple steps and corrections ranging from tens of nanoseconds to a few hundred picoseconds. [...]

A new search for the $K_{L} \to \pi^0 \nu \overline{\nu}$ and $K_{L} \to \pi^{0} X^{0}$ decays

We searched for the $CP$-violating rare decay of neutral kaon, $K_{L} \to \pi^0 \nu \overline{\nu}$, in data from the first 100 hours of physics running in 2013 of the J-PARC KOTO experiment. One candidate event was observed while $0.34\pm0.16$ background events were expected. [...]

Curious Link of Exclusive and Inclusive CPV in Charmless 3-body B$^+$ Decays
/ Hou, George W.-S. (Taiwan, Natl. Taiwan U.)
The LHCb experiment has measured CP violation (CPV) across the Dalitz plot of charmless decays of B+ mesons to 3 charged tracks, namely in K{\pi}{\pi}, KKK, {\pi}{\pi}{\pi} and {\pi}KK final states, with strikingly large CPV that vary strongly with Dalitz variables. Identifying these processes with b -> sqq(bar), sss(bar) and b -> dqq(bar), dss(bar), where q = u, d, then the "sum rule" that requires two-loop absorptive parts by unitarity works well for inclusive b -> s CPV, but less well for inclusive b -> d case. [...]

New Physics Searches at Kaon and Hyperon Factories

(Los Alamos) ; Bansal, Saurabh (Cincinnati U.) ; Bauer, Martin (Durham U., ICC) ; Brod, Joachim (Cincinnati U.) ; Chobanova, Veronika (Santiago de Compostela U., IGFAE) et al.
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths and the availability of very large datasets. [...]
