We introduce an in-depth study of unprobed phenomenological minimal supersymmetric Standard Model region offering a natural solution to dark matter. Since the 1980s this has been referred as “bulk,” consisting sub 200 GeV neutralinos and right-handed smuons. The bulk satisfies recent muon <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:msub><a:mi>g</a:mi><a:mi>μ</a:mi></a:msub><a:mo>−</a:mo><a:mn>2</a:mn></a:math> measurements sustains consistency with all presently...

Summary Experimental methods and theoretical analysis are employed to investigate effects of channel opening area on downward flame spread characteristics extruded polystyrene (XPS) thermal insulation materials building facade. The average height first drops then rises as dimensionless (the ratio sidewall area, ie, S * ) increases. As rises, both the maximum temperature curtain wall decrease, decreasing is linear. XPS surface history can be divided into four stages, inapparent rising stage...
As requirement of Jiangmen Underground Neutrino Observatory (JUNO), the radon activity in high purity nitrogen which is generated from purification system should be measured. The measurement contains a detection chamber and enrichment to measure higher than 3.873 μBq/m3 has been developed for this purpose. result measurement, relationship between collection efficiency voltage supplied calibrated, background 13.53 ± 0.82 mBq/m3 (stat.+syst.) 51% under 25 standard liter per minutes flow speed....
A nitrogen purification pilot plant has been developed to meet the requirements of high purity used in Jiangmen Underground Neutrino Observatory (JUNO). The radon content dropped from (20.5 ± 0.9) mBq/Nm3 (statistical error) (25.2 4.5) μBq/Nm3 (stat.) after purification. Rn reduction factor was estimated be 813 under condition 20 activity. Another experimental result showed that activity (61.6 7.5) (19.2 2.1) flew out plant. It shows purified by meets cleanliness requirement JUNO and would...
We introduce an in-depth study of unprobed pMSSM region offering a natural solution to dark matter. Since the 1980s this has been referred as "bulk", consisting sub 200 GeV neutralinos and right-handed smuons. The bulk satisfies recent muon $g_{\mu}-2$ measurements sustains consistency with $all$ presently operating SUSY experiments LHC constraints. Initial ingress into will arrive soon via LUX-ZEPLIN 1000-day experiment. Observation these light smuon events could optimistically occur at...
Summary In this work, cone calorimeter tests were conducted to investigate fire properties of interior materials (floor covering [FC], aluminum plate covered with paint [APCP], light diffuser [LD], and gel coat [GC]) used in low‐floor light‐rail trains. Ignition time ( t ig ) each material decreases the increase radiative heat flux. The decreasing order four samples by ignition under same flux is LD > APCP FC GC. release rate (HRR), peak value HRR (PHRR), from PHRR p ), growth index...
Dark Matter (DM) residing in a secluded sector with suppressed portal interaction could evade direct detections and collider searches. The indirect provide the most robust probe to this scenario. Depending on structure of dark sector, novel DM annihilation spectra are possible. shower is common phenomenon for particles which take part strong interactions boosted. In terms simplified two-component models vector pseudoscalar interaction, we study showering effects detection. those models,...
We propose the family universal $U(1)_X$ models with three right-handed neutrinos by choosing gauge symmetry as a linear combination of $U(1)_Y\times U(1)_χ$ $SO(10)$. To be consistent quantum gravity effects, we introduced Dirac fermion $χ$ dark matter candidate, which is odd under gauged $Z_2$ after breaking. The isospin violation $f_n/f_p = -0.7$ can realized naturally, and thus LUX, PANDAX, XENON1T experimental constraints evaded. Moreover, study masses mixings for Higgs bosons, consider...

Interestingly, SESM simultaneously explain B anomaly, muon anomalous magnetic moment, mass matter, etc. Also, we study unitarity constraint in this model. perform systematic study, find viable parameter spaces these evade all current experimental constraints. To be complete,...
We propose the family universal $U(1)_X$ models with three right-handed neutrinos by choosing gauge symmetry as a linear combination of $U(1)_Y\times U(1)_{\chi}$ $SO(10)$. To be consistent quantum gravity effects, we introduced Dirac fermion $\chi$ dark matter candidate, which is odd under gauged $Z_2$ after breaking. The isospin violation $f_n/f_p = -0.7$ can realized naturally, and thus LUX, PANDAX, XENON1T experimental constraints evaded. Moreover, study masses mixings for Higgs bosons,...

And thus have DM co-annihilation process mediated by boson, couples exclusively to CP-even CP-odd This is a brand feature compared previous study. For CP conserving case, present...

We propose Generalized No-Scale Supergravity, the simplest scenario for Effective Super-Natural Supersymmetry, naturally solving supersymmetry electroweak fine-tuning problem and including natural dark matter. A light right-handed slepton bulk region is realized in $\mathcal{F}$-$SU(5)$ pMSSM. The may be beyond LHC reach, though can probed at 1000-day LUX-ZEPLIN, Future Circular Collider (FCC-ee) CERN, Electron Positron (CEPC), Hyper-Kamiokande.
