TRANSVERSE MOMENTUM SPECTRUM OF NEUTRAL ELECTROMAGNETIC PARTICLES PRODUCED AT THE CERN PROTON ANTI-PROTON COLLIDER

Forward shower counters equipped with position detectors able to locate to +/- 2mm have been used to measure an inclusive p_t distribution in the rapidity range 1.6<|y|<2.5 for neutral electromagnetic particles produced in proton-antiproton collisions at sqrt(s)=540 GeV. The covered p_t range extends up to 12 GeV/

Experimental observation of isolated large transverse energy electrons with associated missing energy at s=540 GeV

The aim of this study was to determine the association of hormone levels with the occurrence of musculoskeletal pain. Men ages 40 to 79 years were recruited from population registers in 8 European centres. Subjects were asked to complete a postal questionnaire, which enquired about lifestyle and the occurrence of musculoskeletal pain over the past month. Total testosterone (T), oestradiol (E2), luteinising hormone (LH), and follicle-stimulating hormone (FSH) were assayed from a fasting blood sample. The association between pain status and hormone levels was assessed using multinomial logistic regression with results expressed as relative risk ratios (RRR) and 95% confidence intervals (CI). A total of 3206 men had complete data on pain status. Of these, 8.7% reported chronic widespread pain (CWP), whereas 50% had some pain although not CWP and were classified as having some pain. T and E2 were not associated with musculoskeletal pain, whereas significant differences in LH and FSH levels were found between pain groups. After adjustment for age and other possible confounders, the association between pain status and both LH and FSH persisted. Compared with those in the lowest tertile of LH, those in the highest tertile were more likely to report some pain (vs no pain, RRR = 1.28; 95% CI 1.09 to 1.50) and also CWP (vs no pain, RRR = 1.51; 95% CI 1.10 to 2.07). Similar results were found for FSH. Gonadotrophins, but not sex steroid hormone levels, are associated with musculoskeletal pain in men. Higher levels of gonadotrophins but not androgens were significantly associated with musculoskeletal pain in men. Alterations in hypothalamic–pituitary–testicular feedback mechanisms may play a role in the onset of chronic widespread pain
