AFTER MORE THAN TWO DECADES OF INTENSE RESEARCH, THE COMBINED RESULT OF A DOZEN EXPERIMENTS WITH SOLAR, ATMOSPHERIC AND MAN-MADE NEUTRINOS IN NUCLEAR REACTORS AND ACCELERATORS IS EVIDENCE THAT NEUTRINOS HAVE MASS AND OSCILLATE. THE OBSERVATION OF THE OSCILLATION MODES KNOWN AS SOLAR AND ATMOSPHERIC HAS ALLOWED THE ESTIMATION OF PARAMETERS (THETA_12, DELTA M212) AND (THETA_23, DELTA M223) RESPECTIVELY. RECENTLY THE CONNECTION BETWEEN THE TWO, MEDIATED BY THE THETA_13 MIXING ANGLE, HAS BEEN MEASURED WITH GREAT T2K PRECISION AND REACTOR EXPERIMENTS. THE MEASURE OF THETA_13 WAS ESSENTIAL FOR A POSSIBLE DISCOVERY OF VIOLATION OF THE SYMMETRY LOAD PARITY (CP) IN THE LEPTONIC SECTOR. THE T2K EXPERIMENT IN JAPAN BEGAN TAKING DATA IN DECEMBER 2009 AND CONSISTS OF A MUONICON NEUTRINO BEAM PRODUCED BY A NEW, POWERFUL, ACCELERATOR LOCATED IN TOKAI, 150 KM FROM TOKYO, AND SENT TO THE SUPER-KAMIOKANDE (SK) DETECTOR, 295 KM AWAY. TO DATE THE STUDY OF THE DOMINANT OSCILLATION NUMU/NUTAU (DISAPPEARANCE OF NUMU¿S) HAS ALLOWED TO REDUCE THE ERRORS OF THE ATMOSPHERIC PARAMETERS, WHILE THE STUDY OF THE SUBDOMINANT OSCILLATION NUMU/NUE HAS ALLOWED THE MEASUREMENT OF THETA_13 AND FIRST MEASURES OF VIOLATION OF CP BY OBSERVING AN EXCESS OF OUR OWN OVER THE EXPECTED BACKGROUND NOISE. THE PRECISE MEASUREMENT OF THE TOTAL FLOW, COMPOSITION AND ENERGY SPECTRUM OF THE NEUTRINO BEAM IS ESSENTIAL FOR THIS PURPOSE BEFORE THE NEUTRINO BEAM OSCILLATES, AS WELL AS THE EXPECTED BACKGROUND NOISE. THIS IS POSSIBLE THANKS TO A SOPHISTICATED DETECTOR, LOCATED 280 M FROM THE SOURCE (ND280). THE RESEARCH PROJECT HERE PROPOSED CONSISTS OF PARTICIPATION IN THE T2K EXPERIMENT, AND MORE SPECIFICALLY IN ND280. THE IFAE GROUP HAS MADE SIGNIFICANT CONTRIBUTIONS TO THE EXPERIMENT: DESIGN, CONSTRUCTION AND CALIBRATION OF THE TRACE DETECTOR, CONSISTING OF THREE TEMPORARY PROJECTION CAMERAS (TPCS); CALIBRATION, SIMULATION AND RECONSTRUCTION SOFTWARE; AND FINALLY ANALYSIS OF THE DATA. THIS WORK, IN CONJUNCTION WITH OTHER TASKS CARRIED OUT IN CALIBRATION, AND THE RECONSTRUCTION SOFTWARE, PLACES US IN AN EXCELLENT SITUATION TO HAVE AN OUTSTANDING IMPACT ON THE EXPERIMENTAL PROGRAM. IN THE PROJECT PRESENTED WE WANT TO HIGHLIGHT OUR CONTRIBUTION IN THREE MAIN LINES OF WORK: CALIBRATION OF TPC, CONTINUATION OF CURRENT ANALYSES IN NEUTRINO INTERACTIONS AND SEARCH FOR STERILE NEUTRINOS. AT THE SAME TIME THE FIELD BEGINS TO EVOLVE RAPIDLY TOWARDS THE NEXT GENERATION OF NEUTRINO EXPERIMENTS WITH TWO FUNDAMENTAL OBJECTIVES: PRECISE MEASURE OF THE CP PHASE AND THE DETERMINATION OF THE ORDINATION OF THE NEUTRINO MASS STATES. BOTH OBJECTIVES CAN BE ACHIEVED WITH A NEW GENERATION OF EXPERIMENTS WITH MEDIUM (300KM) OR LONG DISTANCE (>1000KM) ACCELERATORS. THE R & D OF THESE EXPERIMENTS IS BEGINNING RIGHT NOW AND IFAE TOGETHER WITH CIEMAT HAS CONSIDERED THAT IT IS TIME TO START THE COLLABORATION. Of PROJECTS, R&D OF A GREAT TANK OF LIQUID ARGON IN THE CERN (WA105) PARE THE MORE ADECTED FOR THE EUROPEAN FURNITURE Around THE EUROPEAN LABORATORY OF PARTICULS, IS A TECHNOLOGY WITH POTENTIAL AND FUERATOR OF THE PARTICULES FISIC.

TRAS MAS DE DOS DECADAS DE INTENSA INVESTIGACION, EL RESULTADO COMBINADO DE UNA DECENA DE EXPERIMENTOS CON NEUTRINOS SOLARES, ATMOSFERICOS Y PRODUCIDOS POR EL HOMBRE EN REACTORES NUCLEARES Y EN ACELERADORES ES LA EVIDENCIA DE QUE LOS NEUTRINOS TIENEN MASA Y OSCILAN. LA OBSERVACION DE LOS MODOS DE OSCILACION CONOCIDOS COMO SOLAR Y ATMOSFERICO HA PERMITIDO LA ESTIMACION DE LOS PARAMETROS (THETA_12, DELTA M212) Y (THETA_23, DELTA M223) RESPECTIVAMENTE. RECIENTEMENTE LA CONEXION ENTRE AMBOS, MEDIADA POR EL ANGULO DE MEZCLA THETA_13, SE HA MEDIDO CON GRAN PRECISION POR T2K Y EXPERIMENTOS DE REACTORES. LA MEDIDA DE THETA_13 ERA ESENCIAL PARA UN POSIBLE DESCUBRIMIENTO DE VIOLACION DE LA SIMETRIA CARGA PARIDAD (CP) EN EL SECTOR LEPTONICO. EL EXPERIMENTO T2K, EN JAPON COMENZO A TOMAR DATOS EN DICIEMBRE DE 2009 CONSISTE EN UN HAZ DE NEUTRINOS MUONICOS PRODUCIDO POR UN NUEVO, POTENTE, ACELERADOR SITUADO EN TOKAI, A 150 KM DE TOKIO, Y ENVIADO HACIA EL DETECTOR SUPER-KAMIOKANDE (SK), A 295 KM DE DISTANCIA. HASTA LA FECHA EL ESTUDIO DE LA OSCILACION DOMINANTE NUMU/NUTAU (DESAPARICION DE NUMU¿S) HA PERMITIDO REDUCIR LOS ERRORES DE LOS PARAMETROS ATMOSFERICOS, MIENTRAS QUE EL ESTUDIO DE LA OSCILACION SUBDOMINANTE NUMU/NUE HA PERMITIDO LA MEDIDA DE THETA_13 Y PRIMERAS MEDIDAS DE VIOLACION DE CP MEDIANTE LA OBSERVACION DE UN EXCESO DE NUE¿S SOBRE EL RUIDO DE FONDO ESPERADO. PARA ELLO RESULTA ESENCIAL LA MEDIDA PRECISA DEL FLUJO TOTAL, COMPOSICION Y ESPECTRO ENERGETICO DEL HAZ DE NEUTRINOS ANTES DE QUE ESTE OSCILE, ASI COMO EL RUIDO DE FONDO ESPERADO. ESTO ES POSIBLE GRACIAS A UN SOFISTICADO DETECTOR, SITUADO A 280 M DE LA FUENTE (ND280). EL PROYECTO DE INVESTIGACION AQUI PROPUESTO CONSISTE EN LA PARTICIPACION EN EL EXPERIMENTO T2K, Y MAS CONCRETAMENTE EN ND280. EL GRUPO DEL IFAE HA REALIZADO CONTRIBUCIONES SIGNIFICATIVAS AL EXPERIMENTO: DISEÑO, CONSTRUCCION Y CALIBRACION DEL DETECTOR DE TRAZAS, CONSTITUIDO POR TRES CAMARAS DE PROYECCION TEMPORAL (TPCS); SOFTWARE DE CALIBRACION, SIMULACION Y RECONSTRUCCION; Y FINALMENTE ANALISIS DE LOS DATOS. ESTE TRABAJO, EN CONJUNTO CON OTRAS TAREAS REALIZADAS EN LA CALIBRACION, Y EL SOFTWARE DE RECONSTRUCCION, NOS COLOCA EN UNA EXCELENTE SITUACION PARA TENER UN IMPACTO DESTACADO EN EL PROGRAMA EXPERIMENTAL. EN EL PROYECTO PRESENTADO QUEREMOS DESTACAR NUESTRA CONTRIBUCION EN TRES LINEAS DE TRABAJO PRINCIPALES: CALIBRACION DE LA TPC, CONTINUACION DE LOS ANALISIS ACTUALES EN INTERACCIONES DE NEUTRINOS Y BUSQUEDA DE NEUTRINOS ESTERILES. AL MISMO TIEMPO EL CAMPO EMPIEZA A EVOLUCIONAR RAPIDAMENTE HACIA LA SIGUIENTE GENERACION DE EXPERIMENTOS DE NEUTRINOS CON DOS OBJETIVOS FUNDAMENTALES: MEDIDA PRECISA DE LA FASE DE CP Y LA DETERMINACION DE LA ORDENACION DE LOS ESTADOS DE MASA DE LOS NEUTRINOS. AMBOS OBJETIVOS SE PUEDEN OBTENER CON UNA NUEVA GENERACION DE EXPERIMENTOS CON ACELERADORES A MEDIA (300KM) O LARGA DISTANCIA (>1000KM). EL I+D DE ESTOS EXPERIMENTOS ESTA COMENZANDO EN ESTOS MOMENTOS Y EL IFAE JUNTO CON EL CIEMAT HA CONSIDERADO QUE ES EL MOMENTO PARA COMENZAR LA COLABORACION. DE LOS PROYECTOS PROPUESTOS, EL R&D DE UN GRAN TANQUE DE ARGON LIQUIDO EN EL CERN (WA105) PARECE EL MAS ADECUADO PORQUE AUNA ESFUERZOS EUROPEOS ALREDEDOR DEL LABORATORIO EUROPEO DE PARTICULAS, ES UNA TECNOLOGIA CON POTENCIAL DENTRO Y FUERA DE LA FISICA DE PARTICULAS. AMBOS GRUPOS TIENEN EXPERIENCIA PREVIA EN ESTE TIPO DE TECNOLOGIA QUE PUEDE AUMENTAR EL IMPACTO DE SU CONTRIBUCION. (Spanish)
