This proposal, submitted in response to the 2014 invitation from STFC, aims to provide and operatea computing Grid for the exploitation of LHC data in the UK. The success of the current GridPPCollaboration will be built upon, and the UK's response to production of LHC data in the period April2016 to March 2020 will be to ensure that there is a sustainable infrastructure providing "DistributedComputing for Particle Physics"We propose to operate a distributed high throughput computational service as the main mechanismfor delivering very large-scale computational resources to the UK particle physics community. Thisfoundation will underpin the success and increase the discovery potential of UK physicists. We willoperate a production-quality service, delivering robustness, scale and functionality. The proposal isfully integrated with international projects and we must exploit the opportunity to capitalise on theUK leadership already established in several areas. The Particle Physics distributed computing servicewill increasingly be integrated with national and international initiatives.The project will be managed across various domains and will deliver the UK's commitment to theWorldwide LHC Computing Grid (WLCG) and ensure that worldwide activities directly benefit the UK.By 2015, the UK Grid infrastructure will have expanded in size to 50,000 cores, with more than 35PetaBytes of storage. This will enable the UK to exploit, in an internationally competitive way, theunique physics potential of the LHC.
