Article Synopsis
  • A search for exclusive two-photon production via photon exchange in proton-proton collisions was conducted using data from the LHC in 2016, focusing on events with intact protons.
  • The analysis aimed to select events with a diphoton invariant mass above 350 GeV, ensuring both protons remained intact to minimize interference from strong interactions.
  • No events meeting the criteria were found, which allowed researchers to set new limits on two anomalous four-photon coupling parameters, revealing |ζ_{1}|<2.9×10^{-13} GeV^{-4} and |ζ_{2}|<6.0×10^{-13} GeV^{-4} at a 95% confidence level.

We describe an analysis comparing the pp[over ¯] elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach.

Unlabelled: The authors share herein their experience in successful treatment of a male patient with multifocal atherosclerosis and lower-limb critical ischaemia complicated by erysipelas.

The Aim Of The Work: to show not only efficacy of iloprost (Ilomedin) used as conservative treatment in patients presenting with critical ischaemia and surgical infection in both pre- and postoperative periods in order to save the limb, but also the possibility of postponing reconstructive intervention, improving the patient's quality of life during this period, as well as shortening the duration of the postoperative period, and also to demonstrate both immediate outcomes of endovascular repair of an abdominal aortic aneurysm and remote results of comprehensive treatment for disseminated multifocal atherosclerosis with severe accompanying pathology.

The first double diffractive cross-section measurement in the very forward region has been carried out by the TOTEM experiment at the LHC with a center-of-mass energy of sqrt[s]=7  TeV. By utilizing the very forward TOTEM tracking detectors T1 and T2, which extend up to |η|=6.5, a clean sample of double diffractive pp events was extracted.
