ABSTRACT This study aimed to investigate the impact of Sharia Supervisory Board (SSB) on Islamic Social Responsibility (ISR) by Commercial Banks in Indonesia. Secondary data were collected from annual reports 14 Indonesia 2010 2020, resulting 125 firm-year data. A panel regression was applied analyze The analysis results show that SSB age, cross-membership, and meeting frequency have a positive...

The $W$ boson mass recently reported by the CDF collaboration shows a deviation from standard model prediction with an excess at $7\sigma$ level. We investigate two simple extensions of extra $U(1)$ dark sector. One is $U(1)_x$ extension, where gauge field mixes through kinetic terms. other general $U(1)_{\mathbf{A} Y+\mathbf{B} q}$ extension model. Fitting various experimental constraints we f...

The neutral component of an inert scalar multiplet with hypercharge can provide a stable dark matter particle when its real and imaginary parts have a splitting mass spectrum. Otherwise, a tree-level dark matter-nucleon scattering mediated by the Z bo-son will be much above the experimental limit. In this paper we focus on a mixed inert scalar triplet dark matter scenario where a complex scalar...

The EDGES experiment has observed an excess trough ($-500^{+200}_{-500}$ mK) in the brightness temperature $T_{21}$ of 21cm absorption line neutral Hydrogen atom (HI) from era cosmic dawn ($z \simeq 17.2$). We consider possible interaction Dark Matter and Energy fluid along with cooling off baryon matter by its collision to explain $T_{21}$. make use three different Matter-Dark (DM-DE) models t...

The fact that most of the Universe is dark and composed of new, exotic components has been established over the years by means of various sets of observations, which recently have converged into a consistent picture where the Universe is about critical and dominated by an exotic form of matter and by an unexpected type of dark energy. In terms of the density parameter Ω, the current view can be...
