Inflammation plays a significant contributory role in the pathogenesis of chronic heart failure (CHF). Many studies have shown enhanced plasma levels of proinflammatory cytokines [i.e. tumour necrosis factor-alpha (TNF-alpha) and interleukin (IL)-6] in patients with CHF. However, there are only few reports on the regulation of anti-inflammatory cytokines(More)
BACKGROUND Inflammation plays a significant contributory role in the pathogenesis of chronic heart failure (CHF). Previous data have shown enhanced plasma levels of proinflammatory cytokines, i.e. TNF-alpha and IL-6, as well as a persistent immune activation in patients with CHF. Furthermore, the immune modulator CD154 has been receiving increased(More)
We report a lattice QCD calculation of the hadronic light-by-light contribution to the muon anomalous magnetic moment at a physical pion mass. The calculation includes the connected diagrams and the leading, quark-line-disconnected diagrams. We incorporate algorithmic improvements developed in our previous work. The calculation was performed on the(More)
The current measurement of muonic g− 2 disagrees with the theoretical calculation by about 3 standard deviations. Hadronic vacuum polarization (HVP) and hadronic light by light (HLbL) are the two types of processes that contribute most to the theoretical uncertainty. The current value for HLbL is still given by models. I will describe results from a(More)
We propose to extend our current B-physics program by computing B-meson weak matrix elements using the new 2+1 flavor domain-wall Iwasaki gauge field configurations with physical light quarks currently generated by the RBC and UKQCD Collaborations. The use of physical light quarks follows the roadmap outlined in USQCD’s 2013 white paper and will allow us to(More)
We propose to compute B-meson weak matrix elements needed to constrain the CKM unitarity triangle and test the Standard Model in the quark flavor sector using the 2+1 flavor dynamical domain-wall fermion gauge field configurations generated by the LHP, RBC, and UKQCD Collaborations and relativistic b quarks. In the upcoming year we aim to finish our(More)
We propose to continue and finish our determination of the B-meson leptonic decay constants fBd and fBs , the B−B0 mixing matrix elements, and their ratio, ξ ≡ fBs √ BBs/fBd √ BBd , on the 2+1 flavor dynamical domain-wall fermion gauge field configurations generated by the LHP, RBC, and UKQCD Collaborations. Using the relativistic heavy quark action we(More)
We calculate the partition function of partially quenched chiral perturbation theory in the epsilon regime at next-to-leading order using the supersymmetry formulation developed by Sharpe and Shoresh. We include a nonzero imaginary chemical potential and show that the finite-volume corrections to the low-energy constants Σ and F for the partially quenched(More)
