Search for heavy resonances decaying into a W or Z boson and a Higgs boson in final states with leptons and b-jets in 36 fb(-1) of root s=13 TeV pp collisions with the ATLAS detector

A search is conducted for new resonances decaying into a W or Z boson and a 125 GeV Higgs boson in the νν¯¯¯bb¯¯, ℓ±νbb¯¯, and ℓ+ℓ−bb¯¯ final states, where ℓ± = e± or μ±, in pp collisions at s√=13 TeV. The data used correspond to a total integrated luminosity of 36.1 fb−1 collected with the ATLAS detector at the Large Hadron Collider during the 2015 and 2016 data-taking periods. The search is conducted by examining the reconstructed invariant or transverse mass distributions of W h and Zh candidates for evidence of a localised excess in the mass range of 220 GeV up to 5 TeV. No significant excess is observed and the results are interpreted in terms of constraints on the production cross-section times branching fraction of heavy W ′ and Z′ resonances in heavy-vector-triplet models and the CP-odd scalar boson A in two-Higgs-doublet models. Upper limits are placed at the 95% confidence level and range between 9.0 × 10−4 pb and 7.3 × 10−1 pb depending on the model and mass of the resonance

Correlation Between Obesity and High Density Lipoprotein Cholesterol (HDL-C) in Breast Cancer Patients of Southern Rajasthan

Despite advances in management of breast cancer, etiology is still elusive. Diet, obesity and other life style factors have been implicated in its etiology. We assessed the role of obesity and HDL-C levels in patients with rural background in etiology of breast cancer. To know the relation between obesity and incidence of breast cancer in local population. Also to know serum HDL-C level in breast cancer and its correlation with breast cancer. A nested pilot study of 50 breast cancer patients was done and matched with 50 healthy women as controls. Obesity was measured by weight, height, BMI (Body Mass Index), waist circumference (WC), Hip Circumference (HC), WC/HC ratio, and Serum High Density Lipoprotein Cholesterol (HDL-C) was measured in patients and in controls. There was no significant difference in distribution of weight (p = 0.298), height (p = 0.653), BMI (p = 0.459) and WHR (p = 0.052) among cases and controls. HDL-C level was observed to be significantly lower in cases than control group (p = 0.017).Breast cancer patients of pre menopausal age had significantly low Weight (p = 0.037) and BMI (p = 0.011) than post menopausal patients. In our study population only low HDL-C level had significant correlation with breast cancer and none of the other anthropometric measurements were associated with breast cancer. However, large population based case control and cohort studies are needed to identify low serum HDL-C as an independent predictor of increased risk of breast cancer
