“…There is abundant astrophysical evidence for the existence of dark matter [1][2][3][4], a nonrelativistic and nonbaryonic matter component of the universe that has so far eluded direct detection through interaction with ordinary matter [5]. Weakly Interacting Massive Particles (WIMPs), which obtain their relic abundance by thermal freeze-out through weak interactions [6], are postulated in a wide variety of viable extensions to the Standard Model of particle physics [7][8][9]. They are a leading candidate to explain dark matter, despite strong constraints from many searches completed and ongoing at colliders [10][11][12][13][14], with telescopes [15][16][17][18][19][20][21], and in underground laboratories [22][23][24][25][26][27][28][29].…”

“…The most popular extensions to the Standard Model of particle physics (9,10,11) produce Weakly Interacting Massive Particles (WIMPs). With the publication of the rst dark matter search results from the LUX-ZEPLIN experiment (12) it is becoming less probable that Dark Matter exists as WIMPs as suggested.…”

The Hubble constant measures the rate of expansion of the universe. Measurements of the Hubble constant, using the flash from the Big Bang, are in conflict with recent measurements using distant exploding stars. This conflict is referred to as the Hubble Tension. The exploding stars measurements also indicate that the rate of expansion of the universe is accelerating. The distance measurement tool is based on the brightness of Cepheid stars in our Milky Way galaxy. Recently, the Gaia satellite which measured the distance of these Cepheid stars from the Earth physically found that their measurements do not coincide with the brightness measurements made by other researchers. The conflict between the two distance measurements of these Cepheid stars has been reviewed (1), declared void and the Hubble tension maintained. Here we show the opposite:- that is, that a different approach to the same data decisively indicates that the Cepheid light is absorbed in the Milky Way. We know that a large amount of the mass of the Milky Way is of an unknown form called Dark Matter. Here we also show that the data of Freedman et al, (2), using stars in the Large Magellanic Cloud indicates strongly that dark matter is the absorber of the star light in both cases. We show that this Dark Matter absorption dismisses the Hubble Tension and the apparent acceleration in the expansion of the Universe. “New Physics” is proposed whereby the Stephen Hawking radiation from the extreme gravitational fields of Black Holes has an additional converse such that Dark Matter particles in the form of binaries absorb the light from the stars. It is shown that the mass of such particles is a billion times the mass of particles that the CERN hadron collider in Geneva can produce: about 2x1013GeV.

It has been shown that a first order confinement phase transition can drastically change the relic dark matter abundance in confining dark sectors with only heavy dark quarks. We study the phenomenology of one such model with a Z′ portal to Standard Model. We find that dark glueballs are long-lived in this setup and dilute the dark matter abundance after their decay to Standard Model. With this effect, the correct relic abundance is obtained with dark matter masses up to $$ \mathcal{O} $$ O (106) TeV. We find that while a part of the parameter space is already ruled out by direct detection and collider searches, there is still a broad space of viable scenarios that can be probed by future experiments.
