HOY EN DIA LA PRINCIPAL MOTIVACION EN FISICA DE PARTICULAS ES LA BUSQUEDA DE NUEVA FENOMENOLOGIA Y NUEVOS PROCESOS QUE PUEDAN EXPLICAR LAS LAGUNAS OBSERVACIONALES Y CONCEPTUALES DEL POR OTRA PARTE MUY EXITOSO MODELO ESTANDAR (ME). ESTOS NUEVOS EFECTOS SE PUEDEN MANIFESTAR COMO NUEVAS PARTICULAS, NUEVAS FUERZAS O BIEN POR PEQUEÑAS DESVIACIONES DEL ME. EN EL GRAN COLISIONADOR DE PROTONES (LHC) SE HA DESCUBIERTO EL HIGGS Y A SU VEZ SE HA PODIDO CONFIRMAR DE MANERA CUALITATIVA SUS ACOPLAMIENTOS RESPONSABLES DE LAS MASAS CON LAS PARTICULAS W, Z, T, B Y TAU. SIN EMBARGO AUN QUEDAN POR RESOLVER MUCHOS MISTERIOS Y PREGUNTAS FUNDAMENTALES. ES PUES AUN POSIBLE Y ESTA AL ALCANCE DEL LHC (ATLAS/MOEDAL) LOGRAR AVANCES SIGNIFICATIVOS MEDIANTE BUSQUEDAS DIRECTAS DE NUEVA FISICA O BIEN REALIZANDO MEDIDAS DE MUY ALTA PRECISION SOBRE MASAS DE PARTICULAS Y SUS ACOPLAMINETOS. EN EFECTO MEDIDAS DE ALTA PRECISION PROPORCIONAN UNA BUENA OPORTUNIDAD PARA TESTEAR Y COMPROBAR LA CONSISTENCIA DE LA TEORIA SUBYACENTE. LA MASA DEL QUARK TOP QUE DETERMINA SU ACOPLAMIENTO CON EL HIGGS (ACOPLAMIENTO YUKAWA) ES DE PATICULAR IMPORTANCIA YA QUE UNA MEDIDA MUY PRECISA DE SU VALOR PERMITIRA CONOCER EL POTENCIAL DEL BOSON DE HIGGS E INCLUSO ENTENDER LA ESTABILIDAD DEL VACIO DEL UNIVERSO._x000D_ _x000D_ EN ESTA PROPUESTA EL GRUPO DEL IFIC ATLAS/FUTUROS ACELERADORES QUIERE FORTALECER SU PAPEL EN LA FRONTERA DE FISICA DE PARTICULAS. EL GRUPO PARTICIPA EN EL DESARROLLO Y OPERACION DE LOS EXPERIMENTOS INTERNACIONALMENTE MAS PUNTEROS DEL MUNDO EN FISICA DE COLISIONADORES. ASI MISMO EL PROYECTO OFRECE UNA CLARA VISION DEL FUTURO DEL CAMPO EN EL QUE ACTIVAMENTE PARTICIPA EL GRUPO, MOSTRANDO SU PAPEL DE LIDERAZGO PARA EL DESARROLLO DE UN COLISIONADOR LINEAL COMO SUCESOR DEL LHC. LA EJECUCION DE ESTE PROYECTO (2019-2021) COINCIDE CON UN PERIODO MUY EXCITANTE DEL CAMPO: 1) EL ANALISIS DE LA GRAN CANTIDAD DE DATOS RECOGIDOS A 13 TEV (120 PB-1); 2) LA PREPARACION DE LA FASE DE ALTA LUMINOSIDAD EN EL LHC (HL-LHC); 3) EL PROCESO DE LA ACTUALIZACION DE LA ESTRATEGIA EUROPEA. NUESTRA SOLICITUD PLANTEA PARTICIPAR EN LOS TOPICOS 1) Y 2) COMBINANDO ADEMAS LA BUSQUEDA DIRECTA DE NUEVA FISICA CON MEDIDAS DE MUY ALTA PRECISION DE PARAMETROS FUNDAMENTALES COMO LA MASA DEL QUARK TOP._x000D_ _x000D_ LAS ACCIONES PRINCIPALES DEL PROYECTO SE PUEDEN RESUMIR EN:_x000D_ _x000D_ - CONSOLIDACION DE LOS ANALISIS DE DATOS EN ATLAS/MOEDAL TANTO EN BUSQUEDAS DE NUEVA FISICA COMO EN MEDIDAS QUE CONFIRMEN LA CONSISTENCIA DEL ME O ENCUENTREN DESVIACIONES; _x000D_ - DESARROLLO, DISEÑO Y ESTUDIOS DE FUNCIONAMIENTO DE DETECTORES DE SILICIO PARA LA RECONSTRUCCION DE TRAZAS EN FUTUROS EXPERIMENTOS E+E-; _x000D_ - PREPARACION Y PARTICIPACION ACTIVA EN LA PROXIMA GRAN INFRAESTRUCTURA DE LA FISICA DE LOS GRANDES ACELERADORES.

THE CENTRAL ISSUE IN PARTICLE PHYSICS TODAY IS THE SEARCH FOR NEW PHENOMENA NEEDED TO ADDRESS SHORTCOMINGS OF THE HIGHLY SUCCESSFUL STANDARD MODEL (SM). THESE NEW EFFECTS CAN MANIFEST AS NEW PARTICLES, NEW FORCES OR DEVIATIONS IN THE PREDICTIONS OF THE SM. THE LARGE HADRON COLLIDER (LHC) HAS NOW DISCOVERED THE HIGGS PARTICLE AND CONFIRMED THE COUPLINGS RESPONSIBLE FOR THE MASSES OF THE W, Z, T, B, AND TAU AT THE QUALITATIVE LEVEL. HOWEVER, MANY MYSTERIES AND FUNDAMENTAL QUESTIONS STILL REMAIN UNSOLVED. SIGNIFICANT ADVANCES ARE IN REACH, WITH THE POSSIBILITIES TO PERFORM DIRECT SEARCHES AT HIGHEST LHC ENERGIES (ATLAS/MOEDAL) AND BY PRECISION MEASUREMENTS OF MASSES AND COUPLINGS OF FUNDAMENTAL PARTICLES. PRECISION MEASUREMENTS OF SUCH FUNDAMENTAL CONSTANTS PROVIDE A UNIQUE WINDOW FOR TESTING THE STRUCTURE AND THUS THE CONSISTENCY OF THE UNDERLYING THEORY. THE MASS OF THE TOP QUARK, WHICH DETERMINES ITS COUPLING TO THE HIGGS BOSON (YUKAWA COUPLING), IS OF PARTICULAR FOCUS, SINCE ITS PRECISE VALUE HAS SIGNIFICANT IMPACT ON THE HIGGS BOSON POTENTIAL AND, ULTIMATELY, ON THE UNDERSTANDING OF THE STABILITY OF THE ELECTROWEAK VACUUM OF THE UNIVERSE._x000D_ _x000D_ WITH THIS PROPOSAL THE ATLAS/FUTURE COLLIDERS GROUP AT IFIC AIMS TO STRENGTHEN ITS POSITION AT THE FOREFRONT OF PARTICLE PHYSICS. THE GROUP PARTICIPATES IN CUTTING-EDGE EXPERIMENTS AT THE WORLD¿S LEADING COLLIDER FACILITIES. THE PROPOSAL ENVISAGES CONTINUITY OF THE EXISTING ACTIVITY AT THE LHC, THE COLLIDER THAT DOMINATES PRESENT-DAY PHYSICS AT THE ENERGY-FRONTIER. IT MOREOVER OFFERS A CLEAR VISION OF A FUTURE FOR THE FIELD AND A LEADING ROLE IN THE PROJECT OF A LINEAR ELECTRON-POSITRON COLLIDER AS A SUCCESSOR TO THE LHC. THE EXECUTION PERIOD OF THIS PROJECT 2019-2021 IS A VERY CHALLENGING TIME: 1) DATA ANALYSIS OF THE RECENTLY COLLECTED 120 PB-1; 2) LHC-PREPARATION FOR HL-LHC; 3) THE NEXT PROCESS OF EUROPEAN STRATEGY PROCESS WITH ITS EARLIEST IMPLEMENTATION. OUR PROPOSAL TACKLES TOPICS 1) AND 3) AND COMBINES DIRECT SEARCHES ANALYSES WITH HIGH PRECISION DETERMINATIONS OF FUNDAMENTAL PARAMETERS LIKE THE TOP-QUARK MASS._x000D_ _x000D_ THE MAIN EXPECTED ACTIONS OF THIS PROJECT CAN BE DIVIDED IN THREE MAIN AREAS:_x000D_ _x000D_ - CONSOLIDATION OF THE ATLAS/MOEDAL DATA ANALYSIS: EXPLOITATION OF THE DATA TAKEN AT THE LHC, BOTH IN DIRECT SEARCHES FOR SIGNATURES OF PHYSICS BEYOND THE SM AND IN PRECISION MEASUREMENTS THAT TEST THE INTERNAL CONSISTENCY OF THE SM. OUR GROUP WILL CONTINUE AND EXTEND ITS STRONG TRACK RECORD IN SEARCHES FOR MASSIVE NEW STATES THAT DECAY TO BOOSTED TOP QUARKS AND IN SEARCHES FOR SIGNATURES OF R-PARITY VIOLATING SUPER-SYMMETRIC MODELS, AND ITS LEADERSHIP IN THE ATLAS EFFORT TO MEASURE THE TOP QUARK POLE MASS WITH A NOVEL TECHNIQUE DEVELOPED BY THE GROUP;_x000D_ - DETECTOR DEVELOPMENT, DESIGN AND CONSTRUCTION: THE GROUP AIMS TO MAXIMIZE TO SCIENTIFIC RETURN OF THE INVESTMENT BY DEVELOPING AND CONSTRUCTING BETTER SILICON/PIXEL DETECTORS. WE ALSO PRETEND TO DEVELOP AND DESIGN A SOLUTION FOR THE FORWARD TRACKER OF A FUTURE ELECTRON-POSITRON COLLIDER EXPERIMENT BASED ON NEXT-GENERATION ACTIVE SILICON PIXEL DETECTORS AND EXPLORE THOSE BASED ON SCINTILLATORS;_x000D_ - PREPARATION OF A NEW LARGE-SCALE COLLIDER FACILITY: THE GROUP AT IFIC IS DEEPLY INVOLVED IN THE LINEAR COLLIDER PROJECT. WE WILL REPRESENT THE LINEAR COLLIDER COLLABORATION IN THE UPDATE OF THE EUROPEAN STRATEGY FOR PARTICLE PHYSICS IN 2019-2020 AND DEVELOP THE BEST STRATEGY FOR ITS EARLY IMPLEMENTATION IN 2021 DEPENDING ON THE RESULT OF THE PROCESS.
