We consider the contribution of the top- and b-quark masses to the Higgs production cross section and to the Higgs pT distribution at LHC.  Join Zoom Meetinghttps://infn-it.zoom.us/j/98020603520?pwd=VDJtenNIZWE1b0dZVC9mbmtpSUd6Zz09Meeting ID: 980 2060 3520Passcode: 338855

The meeting will be held at the Frascati National Laboratory of INFN, in the “Salvini room” (Bldg. 36, map).  

This research involves producing GO using the Hummers method, generating a composite using GO and PVA, and analyzing these composites’ structural, optical, and electrical characteristics. The impact of thermal annealing on the structure and optical characteristics of GO/PVA materials at various concentrations were also investigated. The band gap value, specific resistance, and dielectric constant were all found to be well controlled by varying the thermal annealing temperature and the concentration of GO in this case. To study the effect of temperature on the physical properties of GO/PVA nanocomposite materials with different percentages, all samples were thermal annealed at temperatures of 40°C, 70°C, and 110°C. The exposure to gamma radiation-induced structural modifications in the GO/PVA composite was also studied. The prepared GO and GO/PVA nanocomposite films were subjected to gamma (γ) radiation at different doses (10, 500, and 1500 kGy) to analyze the effects on their structure and optical properties. The structural changes in the nanocomposites were analyzed using X-ray diffraction (XRD), allowing for the determination of any alterations resulting from exposure to radiation at different doses. Furthermore, elemental analysis was conducted using an energy-dispersive spectrometer (EDS) to gain insights into the elemental composition of the samples. The optical properties of the samples were investigated using ultraviolet-visible (UV-Vis), Fourier-transform infrared (FTIR), Raman spectroscopy, and Scanning electron microscope (SEM). These analysis methods provided valuable information regarding any changes induced by gamma radiation.

This is the kickoff meeting of the PRIN 2022K4B58X project “AxionOrigins: towards a complete theory for the origin of the axion” (PI L. Di Luzio) which is a collaborative venture among INFN, University of Padua and Sapienza University of Rome.  The meeting will be held in the Salvini Auditorium (Bldg. 36, access from LNF secondary entrance in Via E. Fermi, 60 – see map).        (Talks by invitation only)You are welcome to download the conference poster here. Aim of the meeting:The aim of the meeting is to establish a collaborative network in association to the PRIN project AxionOrigins. The axion hypothesis, at the interface of particle physics, astrophysics and cosmology, is currently within the reach of experimental verification. However, almost half a century after the conception of the Peccei Quinn (PQ) mechanism, there is not yet a credible theory in which the PQ symmetry arises in a natural way (PQ origin problem). Moreover, the axion solution is notoriously fragile: possible ultraviolet contributions to the axion potential need to be extremely suppressed in order not to spoil the solution of the strong CP problem (PQ quality problem). AxionOrigins aims at identifying extensions of the Standard Model (SM) that incorporate a complete theory of the axion, providing a rationale both for the origin and quality of the PQ symmetry. These include model-building directions that integrate the axion framework with solutions of the SM flavour puzzle based on horizontal gauge symmetries, grand-unified theories and composite dynamics.   Important dates: January    12, 2024 –  Program announcement January …

This seminar will give an overview of the Future Circular Collider Feasibility Study. The luminosity-frontier electron-positron collider (FCC-ee) is part of the proposed Future Circular Collider (FCC) programme which consists of FCC-ee followed by an energy-frontier hadron collider (FCC-hh). This study is well aligned with the 2020 Update of the European Strategy for Particle Physics that requested a global feasibility study of a future 100 TeV hadron collider at CERN, with an electron-positron Higgs and electroweak factory as a possible first stage.  The latest accelerator layouts and beam parameters for FCC-ee and FCC-hh with the R&D for key technologies prepared for the mid-term review  will be presented.The progress in the interaction region and machine-detector-interface design, where the Italian contribution with INFN-Frascati has a well-established leading role will be discussed. Join Zoom Meetinghttps://infn-it.zoom.us/j/95274769209?pwd=cm82R2dsd3hxZ2Q3VTVsMGhOQ3dQdz09Meeting ID: 952 7476 9209Passcode: 774691

The symposium has the aim to gather experimentalists and theorists working in the field of exotic atoms, in particular in kaonic atoms, to discuss the outcome of the ongoing experiments in this sector and plan future activities. The impact of kaonic atoms studies in particle and nuclear physics, as well as in astrophysics and foundation of physics, with an excursus in beyond Standard Model physics search, will be addressed.In the evening of 28th November a public event will be organized at Sala degli Specchi – Comune di Frascati (more infos will be provided soon).The symposium is organized with the support of the INFN-LNF, the John Templeton Foundation (Grant 62099), the STRONG-2020 EU project (grant agreement No 824093), the MITIQO project n. A0375-2020-36647,“Gruppi di ricerca 2020” – POR FESR Lazio 2014-2020 and FWF Austria, project n.

The SESAME Proposal Review Committee (PRC) is an international advisory body, established by the SESAME Director to provide counsel regarding the allocation of user beam time. The PRC undertakes this responsibility by thoroughly assessing the scientific and technological merit of proposals submitted by the General Users (GUs) and ascertaining their priority. This assessment is guided by criteria aligned with IUPAP’s Recommendations for the Use of Major Physics Users Facilities. The forthcoming PRC meeting is scheduled to convene in Frascati.
