Higgs pair production with SUSY QCD correction: revisited under current experimental constraints
We consider the current experimental constraints on the parameter space of
the MSSM and NMSSM. Then in the allowed parameter space we examine the Higgs
pair production at the 14 TeV LHC via ( is the 125 GeV
SM-like Higg boson) with one-loop SUSY QCD correction and compare it with the
production via . We obtain the following observations: (i) For the
MSSM the production rate of can reach 50 fb and thus can be
competitive with , while for the NMSSM has a much
smaller rate than due to the suppression of the
coupling; (ii) The SUSY-QCD correction to is sizable, which
can reach for the MSSM and for the NMSSM within the
region of the Higgs data; (iii) In the heavy SUSY limit (all soft mass
parameters become heavy), the SUSY effects decouple rather slowly from the
Higgs pair production (especially the process), which, for TeV and TeV, can enhance the production rate by a factor of
1.5 and 1.3 for the MSSM and NMSSM, respectively. So, the Higgs pair production
may be helpful for unraveling the effects of heavy SUSY.Comment: discussions and references added, accepted by JHE
Rosmarinic Acid Prevents Cisplatin-Induced Liver and Kidney Injury by Inhibiting Inflammatory Responses and Enhancing Total Antioxidant Capacity, Thereby Activating the Nrf2 Signaling Pathway
Drug-induced liver and kidney damage is an emergent clinical issue that should be addressed. Rosmarinic acid (RA) has obvious anti-inflammatory and antioxidant effects, so we evaluated the anti-inflammatory and antioxidant effects of RA pretreatment on serum and liver and kidney tissues of cisplatin (CP)-treated mice and explored the possible mechanisms. The results showed that RA pretreatment effectively downregulated the serum, liver, and kidney levels of ALT, AST, BUN, and CRE and the inflammatory factors IL-1β, IL-6, and TNF-α, and simultaneously enhanced the total antioxidant capacity of the liver and kidney. RA pretreatment significantly reduced the levels of MPO, MDA, and NO in liver and kidney tissue, inhibited the mRNA expression of IL-1β, IL-6, and TNF-α in liver and kidney tissue, activated the Nrf2 signaling pathway, and upregulated the mRNA expression of downstream target genes. Our findings show that RA could effectively prevent and alleviate acute liver and kidney injury caused by CP
The First Calculation for the Mass of the Ground Glueball State on Lattice
Under the quenched approximation, we perform a lattice calculation for the
mass of the ground glueball state in channel on a
lattice. Our calculation shows that the mass of this state is
, which rules out the or mainly
glueball interpretation for .Comment: 10 pages and 1 figur
