The Experimental Physics at High Energy Colliders group is made up of 50 physicists, both from the CSIC and the Universitat de València. This is a consolidated group since the 1980s. Its members have contributed to the construction and operation of experiments at the most relevant colliders in the field. For example: PETRA (DESY, Germany), LEP (CERN, Switzerland), Tevatron (FERMILAB, USA), PEPII (SLAC, USA), KEK (Japan) and LHC (CERN, Switzerland). Experiments associated with these accelerators have discovered new particles such as the top quark and the Higgs boson. They have also contributed to the present understanding of the Standard Model of Physics. 

The group is currently participating in the ATLAS and LHCb operating experiments at CERN. 

In the same way, this group is highly involved in the design and development of the main future tools in the field such as: the modernisation and upgrading for high luminosity of the LHC (ATLAS and LHCb) as well as the possible future linear colliders: ILC and CLIC. The involvement not only concerns data analysis and detector operation, but also the development of analysis tools (including grid computing, GRID), detector development and the accelerator technology itself. This optimises resources and maximises the impact of our group in the experiments in which it participates in order to be internationally competitive. 

The main lines of the group are: detector instrumentation, data analysis and simulation, distributed computing (GRID), accelerator technology. 

The group has extensive experience in detector instrumentation and has been a pioneer in Spain in the use of silicon detectors for trace and vertex reconstruction in particle physics experiments, in close collaboration with the Barcelona Microelectronics Institute (IMB-CNM). 

A clean room is available for the development of silicon detectors (strips and pixels). The accumulated experience has allowed the transfer of this technology to applications in medical physics and detector instrumentation in other fields. 

The group contributed to the construction of the trace reconstruction system at ATLAS and we are involved in the new system for HL-LHC and the readout electronics of the LHCb trace detector. We have extensive experience in the operation of this detector and leadership in both operation and data analysis. We are also involved in the construction of the new Belle II vertex detector with DEPFET technology with applications at the future linear collider (ILC or CLIC). 

Importantly, the group is involved in the operation of the ATLAS and LHCb detector and in many of the analyses using data from these experiments. The physics of the top quark and Higgs boson, the direct search for Supersymmetry and the search for new physics through flavour processes with b and c quarks are the context of our main scientific activities in data exploitation. 

The group has high visibility in the LHC and ILC/CLIC projects. In the case of flavour physics, the discovery of T-symmetry violation is an original contribution of ours. These activities will be continued in the coming years. The TIER-2 infrastructure for distributed computing (GRID) of ATLAS has enabled the group to have a major impact on data processing. This creates the right synergies for the analysis activities to have an impact within the experiments, as well as other applications and technology transfer derived from this activity to other fields, such as medical physics, etc. 

Likewise, our group has an incipient and very active role in accelerator physics. It has already made notable contributions to the design and optics of accelerators as well as to the instrumentation for monitoring the beams of the LHC (HL-LHC) and the new linear accelerators: ILC and CLIC. In this field, we have significant initiatives in the field of medical physics.
